Ok, lets start from the top 
Your website is currently lacking doctype, which is very important. if you choose the most forgiving doctype html 4.01 transitional, then your website have 104 errors according to W3.org’s HTML validator.
You have added several stylesheet declarations directly into the page instead of linking to one CSS file remotely and for some reason you have a < /center> in the middle of one of them (?!).
Your layout is flat and your choice of colors are to full of contrast to be attractive. A black background brings thoughts to something dark and brooding, which most people associate with shady operations and foul play. Not really the emotions you wish to evoke.
Instead of using tables you should make a nice layout. A simple layout is very easy to do in photoshop or you can purchase a ready made professional template for around $50. What you have now look a bit…80’s
You have a good start, but it can be much improved. Good luck and best wishes on your project
