Yeah I know, I'm just playing along as well. So if you were to pick all the parts yourself and cover that, the only real work left would be:
1. Merging them together
2. Optimising to a Good rating
The former would take a few minutes per item so likely not that expensive, but optimising is a very broad activity that can either be really shitty or really professional. For example, if an avatar has too many dynbones (wiggly physics, secondary motions), one could optimise it quickly by simply deleting the bones and making it stiff, or much more intricately by selectively merging them and reworking the values to look as natural as it did originally. There's a big range there where you will get more as you pay more, basically.

But really though? Make some friends with the people in here and slowly ask them for advice as you go along, because in this community most people really do that sort of thing for themselves.
