incorporate stripe payment system to custom site - replace existing gateway

we need someone to replace existing payment gateway system within our site. It will require sending information to [login to view URL], then receiving the response to upgrade a person's quote to an order. Our site is a modified CreLoaded (OS Commerce) site. HOW OUR SYSTEM WORKS: 1) We receive orders from customers initially without any payment required (it is treated as a quote request). ORDER STATUS: SENT 2) We check details and add the shipping cost and advise the customer of the overall cost etc. ORDER STATUS: READY TO ORDER 3) Customer returns to the quote/order in their account area and fills in credit card information. If their payment is successful the order will update to ORDER STATUS: ORDERED It is in step 3 above that we need the credit card information to be sent to Stripe. We have previously been using a different payment gateway (IPG/ST George Bank) which is already incorporated in to the system but needs to be replaced. We are looking for a developer that is already familiar with the Stripe payment system and must see current examples of similar works. see here for our website: [login to view URL] see here for more info in the Stripe system: [login to view URL]
