It looks like there's been an update since some of the above comments as I'm getting black, not white text. But the yellow is too bright for either of them in my opinion.
Bar 3 lines of description (and the menu) the front page is all adverts- if I was visiting your site for the first time I'd assume it was one of those sites with adverts on every page and head straight for the back button.
I think the header is very well done, and looks professional. And the actual design of the site is good, apart from that yellow.
