Simple Website/CSS Bug Remover Needed

Hello Website Bug Fighters! I need an expert CSS developer to remove bugs from my blog [login to view URL] This week, while adding new CSS into my blog, adsense (image/text) has become problematic. Frankly speaking, I have installed CSS from free template sites and after installation, while clicking image/text Google ads, the links do not follow/redirect to the URLs of the given site. Again, if I click a linked page or a post " Page not found" shows. Please help checking the blog and say me what to do and bid as low as possible. I am not a professional web developer but having a bit knowledge on blogging. The project is open worldwide. However, bidders from US, EU are desired but not mandatory. Plz. respond soon. Thanks.
