Build an Online Store

We are looking for a company o person with solid experience in payment integration (2checkout, Paypal, Banwire) for Prestashop e-commerce. We are a mexican company with a commerce plattform in Prestahop release 1.6.0.9 We are processing payment with two companies: 2checkout and Banwire (mexican Company) and we have the following needs: 2checkout. Currently we are receiving payments however a very big problem we have is that purchase order is not created in prestahop. We need that all of the parameters will be returned to our backoffice. We would like that 2checkout be the main payments integrator for our Company, so I need mentoring step by step for this. We are processing payments through ckeckout plattform but in short term we need that all of the payments are processed in our own domain (we know that a SSL certificate is needed). Also we like customized fields and the processong in a very easy and flexible way for our customers. Banwire: Banwire is working properly however when a payment is refused, no friendly messages are displayed for our customers (only technical codes). We have the “translation” for those codes and we need that messages are displayed for the buyer and problem can be solved. Paypal An addon for paypal exists in Prestahop which allows receive payments however when we tested, a similar problem to 2checkout was found: purchase order is not created in prestahop. We need that all of the parameters will be returned to our backoffice.
