Hi, I was looking around for new projects and decided to bid on yours. I'm specialized on Drupal Commerce (and Ubercart) and payment gateway integration, with Paypal you shouldn't have issues since it is the most used module for this system. I will review all your gateway configuration and all the messages errors on Drupal and PayPal APIs (you will have to give me access to both), then in less than one day it will be probably working all good. My price is already fit for this job.
A little about me, my name is Marcelo and I'm from Brazil. I am a CS graduated with more than 17 years experience in IT market, and +8 years experience with Drupal, mainly development, SEO and performance tuning. I have other some good works at my portfolio. I'm closer to 100% conclusion rate and positive feedbacks here at Freelancer.com and I intend to keep that. I also just became a Preferred Freelancer, which means Freelancer.com trusts and approves my work.
If interested, call me on chat or award this bid!
Regards,
Marcelo.
