I need a clone of 99designs.com or ready made code/script you already have.

I need all functions.
Please make sure you look over the site carefully.

Please do not bid if you are not 100% confident you can finish this job with good quality work on time.

Here is how it works
Phase 1 - Starting the Contest
Contest holders fill out a logo questionnaire and prepay the prize through their credit card, bank account, or PayPal. The contest will go live instantly if paid by credit card. If the contest holder has paid by e-check, the contest will go live within seconds of the e-check clearing. (Usually about 3-4 business days.)

Phase 2 - Entries & Feedback
Once the contest is live, designers will then submit their logo concepts over the coming days. Contest Holders will rank the concepts as well as provide feedback as often as possible. Contest Holder participation is key to a successful contest. The more frequent the feedback and ranking updates, the more entries a contest will receive, and to a higher quality.

Phase 3 - Winner Selection, File Transfer, and Payment
Once the contest has ended the Contest Holder will have 3 days to select the winning designer. This is usually completed the same day. The winning designer will be notified by email, and will upload the final files. The Contest Holder will then download the files and approve them. Once the final files have been approved the prize (less the 10% 99designs commission) will be sent immediately to the designer's PayPal account on file.

I need this complete in 3 weeks time.
