I need help to complete the project. I have the basic idea but don't know what's the best functions I need to make the site running smooth.

For pitching ideas, need submit form and payment function.. For sharks, We need a way to verify their credit, then give password to access contact information. We also need a way to ensure and collect the 1% commission. I thought to use script like freelancer, both parties dealing on our site, so we know when a deal is done and able to collect the 1% commission.

If you sure about what I really need, please give me a quote.Thanks! See what I have done at http://sharklake.com
