First the good...I think you chose a wonderful color of blue for the header. It will be interesting to see what your logo will look like. I also like the icons you used (but I would add labels as I didn`t realize they were links).
Now...the basic layout of the site is functional but I think there is just too much going on. The ads moving on the side, differing ad sizes, and not a lot of your own content on the Homepage makes the site a bit off-putting. Your text gets lost among the ads.
I agree with John49 that the full page ad that took over my screen was enough to make me leave. That is not the ultimate goal of ads. They should peak the users interest but still make them want to use YOUR site.
Also, the search box got lost in the page. I realize there is a Home button above it but that does not appear unless I mouse over it. So there is just white surrounding a white search box and nothing letting me know it`s there.
Please know that i`m not trying to be rude or offensive, I`m just giving feedback to assist you. This site has great potential with a few tweaks.
