Low poly weight paint with auto rig pro (commission?)

I am working on a low poly model for a game. I use the auto rig pro add on for the rigging. Unfortunately, my mesh sometimes pulls on other pieces of the mesh. I need help to weight paint it, but don’t know how to weight paint the different pieces of the mesh to the individual bones of the rig. Can I commission someone to to this for me, or get a video helping me do it for myself?
