This is a huge topic, and a complicated one. I'm not sure how far you've gotten into this process and how much you already know.
My husband is a professional writer who has published 1 book, and his agent has a 2nd one (completed - fiction) and a proposal for a 3rd (non-fiction). He's done pretty much everything you can imagine, but he already had a strong writing background. I don't know if you have that so forgive me if I repeat some things you already know.
If you have no experience, you need a lot more than an idea. You need writing classes. You can see what's available at your adult education center, you can join a writers' collaborative, and more. How you write has a lot to do with what you are writing - for example, a non-fiction analysis of population trends is very different from a non-fiction cookbook, which are both very different from a fiction political satire or a fiction children's book. You need feedback from qualified authors and editors - not just other would-be writers who find you interesting. You need to be able to take the criticism and go back to write again, over and over.
Make sure your idea hasn't already been done. Chances are, it has. Sorry, but that's the truth. You have to be careful not to violate copyright laws, even inadvertently. Copyright lawsuits are very expensive.
Next, even if the idea hasn't been done (or if you have a truly unique twist on it), you still have to be sure you do it thoroughly and that you have excellent writing skills. You also need phenomenal proofreading and grammar abilities, or 2 outstanding people who can do this for you.
Self-publishing is the most expensive but the easiest to accomplish - there's always someone who will take your money and publish your book. But then what? How are you planning to market your book? Book-signings? They are time consuming and you have to provide the books yourself (your cost), hoping people will come, like what you have to say, and lay out the cash. Bookstores? How are you going to get your book in front of enough of them to make back your costs?
Or you can find a publisher - and this is a long, arduous process that is filled with rejection. You need to learn to write a good query letter, a 1 paragraph summary/sales pitch, a 2 page summary, sample chapters, and an outline. You can also find an agent - same process, but they have specialties and their own contacts. You need to learn how to find them, how to rate them (based on your topic) and how to get them to pay attention to you. They will ask for an exclusive and they will sit on your manuscript for months and months - can you afford to wait? Be aware that publishers largely want known authors who are guaranteed to sell. There are no developmental editors anymore - that is, absolutely gone is the old system of having an editor take you under his/her wing to work with you and nurture your book along. Face the reality that the world is not sitting around waiting for your great idea - so you have to find a way to get someone's attention and sell your idea in the middle of an industry filled with people just like you and with publishers who are skeptical of your plan. You need a very thick skin and a strong backbone, and the ability to take rejection and move on.
There is a 3rd option called shared expenses, in which a publisher (usually a smaller one) has an editor who likes your book and is willing to help you, but you pay part of the expenses of publishing. They usually don't have a large PR department so you will have to supplement the inquiries they send out to their industry contacts. Do you know how to do this?
You mention research - do you have sources for this? You can't just use Google - you have no way of evaluating what's out there if you just do random searches. So how will you qualify, evaluate and sort out those sources? You mention organizing - if you are doing a non-fiction book, you might consider using an index professional. I know someone who does this - and I had no idea that it is a specialty until I met her in a women's networking group. So every textbook or other non-fiction book that relies on footnotes and so on also needs someone to put together that index in the back of the book. Huge undertaking. Do you have the finances to afford someone like this?
Depending on how far into your project you are and what topic it is, some of the above may not apply. If you are motivated and if you are really good at seeking out other professionals who can support your strengths and help you in your weak areas, and if you are extremely teachable, you may have a good chance! But it's absolutely not a process for the weak-kneed or the faint-hearted.
