Hey,
My name's Paul. I'm a freelance Programmer, and Web / Graphic Designer.
I do a lotttt of website work, so what you're asking for is right up my alley.
I spotted your post via the freelancer emailer, so I hope my proposal isn't too late!
I read over what you're asking for, took a look at "mrsextstories" but "bdsmlibrary" came up as a reported attack page. Though the first one gave enough detail as to what you're looking for.
If that's the kind of layout and such you want, perfect; that eliminates a whole step of design.
Unless you had something else in mind, that's fine too. Just let me know.
PHP and MySQL are my prime, every day languages. So I can assure you that the files will be uploaded right, validated and sanitized.
A spot for ads like you requested is only natural. We'll have to discuss more on how you want them to be displayed and what exactly you mean by the "I should be able to add advertisers that contain links to the advertisers."
Other than that, I HAVE worked with WordPress, but I honestly don't use it myself.
I code everything from the ground up, so what you want is what you get! : )
I hope we can talk business, and I look forward to your response.
Thanks in advance,
Paul
