I need an escrow service to be developed and placed on a functional marketplace website similar to [url removed, login to view] but for a different industry the major difference is, I need an escrow service to be developed and placed in the website as an application not a third party tool. The communication is currently done by e-mail but now we want to build an application like escrow on the website.
I need all normal features of an escrow service to be present and it should be tamper free. I would like customers to be able to pay with credit cards or any other e-currencies for this method i need it to be developed similarly to Elance's verification where the customer must confirm deposits. Come up with your ideas and experience with the flow of the system.
Timeframe for delivery: will look forward to your suggestions as this is complex and one of the big project. We have another project as well so if this goes well we would like to work on it as well.
