Hey Paulo!
This sounds like the job for a Shopify Expert for sure.
Shopify Experts is an online directory of eCommerce experts that can help you run your Shopify store. From customizing your theme to building custom applications, these experts can help with everything and anything related to Shopify. Many of them trawl the forums looking to help out with shops, but it never hurts to reach out directly to them for assistance with this kind of thing.
Let me know what you think!
