Hi, 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. I have some good works at my portfolio, and other minor websites to send you links if interested. I'm with 100% positive feedbacks here at Freelancer.com and I pretend to keep that.
I read your project and I'm interested on it. I have plenty of experience with Drupal Commerce, but I think this is not the case. You do want a custom payment workflow, and I already had done that before for a educational institute here from Brazil (Is it your case too, courses and training?).
What will you need more, beyond take your customer to the payment gateway? Any stock (or vacancies) control? Do people need to return to site after payment? E-mail sending, internal system workflow (for roles/download/access restrict area/etc)... Anyway, I have to analyze all you want on it (a to-do list would be great, the URL link if it's online too), then I will have to review my price and time expectations. I must warn you, depending on the features you need, that it can become a little higher than I bid here, but probably very around this price.
If all of above sounds good to you, then I hope to hear from you soon.
Regards, Marcelo.
