Product Options with Fastor

Hi Folks,
I am using Fastor theme which we find brilliant. Does anybody recommend a way we can offer customers a simple solution to upload a file when purchasing a particular product…for example “a logo” for us to add to there product…or maybe and option to ADD INITIALS to the product being purchased…I hope this makes sense. I used Product Options before with a different theme but am unsure if there is a smooth way to integrate someting similar in Fastor.
