PHP Web Site Design from scracth

I need someone to write me a php website that will have some features. It must be very secure, not easy to be hacked, and fully functionally. I will elaborate what I want in the website in private message, so you can tell me how much it will cost in total and in how many days you can deliver it. I need someone with good references and with php and mysql knowledge, cus I need is not a job of new-started webmasters. You can bid, bidding money is not important, after I tell you what will be in the web page, you can suggest how much it will cost to me. So, based on your information I will pick up who I will work with. My budget is tight so, if you are thinking too much, you can continue browsing other job posting.
