Custom Drupal Payment Module integrating Poundpay

I'm building a drupal-powered marketplace and need a strong technical partner for custom module development and tech-heavy tasks. Specifically right now I'm looking into developing a custom module that integrates Poundpay ([login to view URL]) with Drupal to handle my marketplace payments. Poundpay has an amazingly simple API to hook into, more info here [login to view URL] Check out [login to view URL] as a reference marketplace that is using Poundpay. Features needed right now: read in conjunction with [login to view URL] 1. When Buyer makes purchase and thus goes into poundpay status "authorized" send email to seller asking him to confirm that he's going to provide the product/service. His confirmation through a button on drupal site or a direct email link then triggers the poundpay status to be set to "escrowed". Now I only want the payment status to be set to "released" (which is when the money is paid out to the seller) 24h after the purchased service was provided. So this I imagine would be triggered through a combination of rules & date. Further functionality needed: For Sellers 1. A view listing to be confirmed bookings with option to cancel booking 2. A view listing confirmed outstanding bookings with option to cancel booking 3. A view listing past bookings and total revenue generated That's it for now.
