The very best evaluation you can get is from a Developmental Pediatrician. You can find them at childrens hospitals. Next best, and still very good, is to get a nureopsychological evaluation and seek treatment from a board certified child psychiatrist, this route may be quicker. You can see the psychiatrist and get the referal for the evaluation from them; while they may be able to make the medical diagnosis without the evaluation data, you want this to confirm the diagnosis and to use to get good educational interventions.
Medication is only one part of treatment, but it is a very important part. It is a tool that you use to make all his therapy more effective. He should be in some combination of Play therapy, Congnative Behavioral Therapy, Social Skills classes, speech therapy, occupational therapy, medical intervention, and school based educational and behavioral interventions.
Proper medication does not alter anything but the undesireable effects of ADHD. I say ADHD, becuase what most people call ADD is actually ADHD-I (inatentive type.) There is no way to tell you which drugs will work for your sons case of ADHD, but if there were an udesired side effect, your medical professional would change the medication. There are many, many choices and one, or more, will probably help your son a great deal and he will benefit much more from all the therapy that you will be paying for, which is important; it can be expensive, even with insurance, so if you can maximize his progress, that will benefit everyone.
If he is having trouble in school, write to the school and request an evaluation. Children with ADHD can have comorbid learning disablities that are more than just a problem with attention. A full evaluation by a Developmental pediatrican or a nueropsycholgist will identify this too. Use your private evaluation to keep the school honest. If he qualifies for intervention, always provide your own services so that he is maximized. The school is not requried to make him anything more than functional.

Read about ADHD- anything by Mel Levine or Russel Barkely will help. They have great strategies and advice, and can describe what is really going on. CHADD should have a chapter in your area, join their support groups. NAMI offers great caregiver resource classes.
Finally, Natural remedies are not shown to be effective, and many are not safe. Save your money if you decided not to provide standard medical treatment with the many different choices that are very safe and effective. Any time you are under a doctors care, you should have easy and quick access to them, and this is one time when you need it more than ever. If you can afford it, find a psychiatrist who does not take any insurance and file it out of pocket. A doctor who is not under any obligation to insurance plans can see you more often. If you can't see the psychiatrist every few weeks while you are trying to get the medication right, you are not going to be as happy with his care. Find someone he can see when he needs to.
We have had nothing but good experiences with our doctors. Not every drug helped our children, but we did find very effective help. Night and day help. First and foremost, ADHD is a medical condition, and we don't stress about our treatment for other flesh and blood systems of the body when something goes wrong. There is no shame in having this disorder, so keep your head held high and get him the treatment that he needs, and don't feel the slightest bit like you are giving up, coping out, or doing things the easy way. There is going to be nothing easy about all his, his therapists, yours, and his teachers hard work for him to get better, it will just be a whole lot harder, slower, and less effective without the medication.
Good luck!
