First of all, maybe someone has or knows where could I get a decently textured FPS arm rig? Also was looking for tutorials or courses about the workflow of modeling, sculpting and texturing human body, arms or hands but with no avail.

Look at LinkedIn learn a course in zbrush then study the human anatomy, I could model and texture an arm rig for you, but it wouldn’t be until next week.

ill find some recourses for you.

Re-texture these it could do the job but note it’s a personal use item.
