Travel Request Website

I want kind a freelancer website but focused for travel requests.\r\nUser end (traveler)\r\n- A page with a web 2.0 design with moving pictures and to sign in with or without facebook integration.\r\n- Up to 4 filed to fill, like: name, travel dates, destination...\r\n- Next steps they will fill up more questions about the trip\r\n- Next page they will have to pay a fee (integration with paypal), so their travel request goes to the database.\r\nProfessional end ( travel agent)\r\n- Access to all travel request. They can access the travel information, but not the traveler info, like email and phone number. If they like they will have a option to buy the lead and then have access to the traveler info.\r\n- Each lead can be bought up to 5 times. So 5 different people may buy the same lead. So if someone buy a lead, then there will only 4 left to buy, if 2 travel agents buy the lead only 3 will be available, and so on... As soon as all 5 are bought, must shows sold out.\r\n- As soon as a lead goes into the database, all travel agents must receive an email with the travel info, but not the traveler email and phone number.\r\n- Travel agents will load credits with paypal account to buy the leads.\r\nAdmin end:\r\n- I may set how many credits each lead is valued (so travel agents can pay)\r\n- Each lead must be approved by admin before becomes available to travel agents\r\n- Establish cupon codes\r\n\r\nFeature:\r\nOn the third step, when the traveler is filling up the travel information, if he/she choose not to pay, and leave the page, an email (provided on the step before)must be sent offering 50% discount on the fee with a cupom code.
