Looking for similar solution to your other clients - a Bitcoin escrow system. I have re-pasted that request below with a couple minor modifications:
I need a simple escrow service, similar to [url removed, login to view] or [url removed, login to view] and integrated with blockchain JSON Rpc api
([url removed, login to view]) to send and receive bitcoin payments.
With the following features:
1) Users will have a bitcoin address generated upon sign up.
2) This address and transaction history will be displayed in the user profile.
3) I would like the customer to have the ease of just transferring bitcoins to their address to deposit money and I would also like the sellers to be able to transfer the bitcoins out after a transaction has been completed.
5) I would like to collect commission on vendor listings when a transaction is completed.
a) I would like the commission to be variable depending on price of listing
b) I would also like the commission percentage go up if the customer/vendor has to go through resolution.
6) I would like to give the option for customers to place a transaction into resolution if they don't receive their product.
7) I would like to set a 30 day auto finalize on the escrow payment if the customer doesn't log back in to finalize the order after receiving their product.
8) I would like the exact same system available for Dogecoin as well.
9) I would like it installed into my current website and tested for functionality.
