Budget Break

I need a website to book a holiday in South Africa. The idea of the site is that the user of the site submits a request linked to a budget. The details are sent to advertisers on the site that registered according to what they can offer. If your offer falls within the clients request parameters, you reply with your offer on the site. The user will then view all the offers on the site and once they see something they are interested in, they will be able to choose to be put into contact with the one offering the deal. The biggest concern is to capture the correct data and to ensure that people are only put into contact with those that offers deals within the specified budget as well as the dates [login to view URL] will not be a typical search site which offers all kinds of holidays and takes time to get a booking done. I do understand that we will need content on the site for optimisation purposes and I need help with that please. I will need a registration form that includes monthly payment options for advertisers, but all bookings will be done directly between client and consumer as I will not charge any booking fees, only monthly subscription fees.
