Hi,
I am a web developer with more than 5 years of experience in PHP, MySQL, HTML5, CSS3 and JavaScript. Therefore, I think I could successfully complete your project, and create an excelent search engine with ads, just like you ask.
I am a fast yet accurate programmer, so I can guarantee I would deliver a great job, so you will not be disappointed.
In my profile you can see some of my previous work. I could give you more examples, if you want to.
I look forward to start working with you.
Regards,
Imanol
