This website is not your best bet for that sort of thing. There are so many companies that do what you are proposing, you really need to find out how to stand out. A clever name is not the key to success.
My husband is an advertising professional, and he would tell you that you need someone with experience in that area - advertising, marketing, branding. He also has an on line business and we know all the pitfalls. You also need website development (for the technical end of things, a payment system, and design/copywriting). Your expertise may well be in the creative end - the monogramming and the design of the products - but it's an entirely different specialty to set up a business and make it visible through Search Engine Optimization, developing followers and newsletter/catalog recipients, and other ways to contact prospective and past customers.
I don't want to offend you, but your question itself has many spelling and punctuation errors, over a dozen in just in a few sentences. Maybe English isn't your first language, maybe you are posting from your phone, maybe you just aren't a good speller - none of those are your fault. But you absolutely cannot make any errors in a commercial site if you want to be taken seriously - your attention to detail on your website lets people know that you have good attention to detail in your products. And of course you may have the most beautiful website in the world, but if no one knows about it, you won't have any business. If you don't have several thousand dollars on hand to get this business launched, I do fear you are doomed to failure. I hate to see you lose your investment. You really have to get involved with professionals who can do the things you cannot do, and concentrate your skills where they are best put to use, in the monogramming and product design areas.
