Hello. These are my questions about the script:

-Is it available in Portuguese? 
I want this script to use it for the Spanish-speaking market, so it is very important for us that the script is available in spanish. But also for the Brazilian market, so would be great if it is available in portuguese. And in english too.

- Is it available other payment gateways like Payoneer or others?
Paypal have restrictions in some Latin American countries. So I would like to integrate the script with Payoneer. Is that possible? Would be great if the payments can be made in cryptocurrencies too...

- Is it available an affiliate program?

I would like that the members of the Frelance site can refer other people. Once they create a project, the referer get a commision. Does the script have this feature?

- Does the script includes future upgrades?

- In the case that the script have bugs, can I get a refund?
