Another user sent me a PM asking about TESU but their settings don't allow me to respond. I'll go ahead and post my response to them publicly, it might be useful for someone else as well.
Hello,
Here's a link to a post I wrote on another forum.

That forum will be your best resource. There are several ways to earn credits quickly and inexpensively. My post will give you a general idea of what you need to do but it's several years old so it will be outdated.
Good luck. It's a daunting task but once you put your mind to it you can knock it out quickly.
