Is there a site that help with corodinating colors because I am not very good at it.

I just did a quick search on google specifying what you said and found this site (its pretty good if you just want to match shades of the same colour)

I also looked for a colour wheel to help you and I found this, it has some useful hints for your site

If you want more sites, just google it, but these are just people's opinions, if its your site why not make it using colours you like and think look good together

It's not a site, but try checking out your local bookstore for a book called "the color index". I had to purchase it for a graphic design course and it's saved my skin so many times; I'm horrible with color-coordinating as well. It's gives RGB And CMYK equivilants of all color combinations. Definitely worth the purchase :)

thanks every one
