I suggest waiting until January/February and then touching base with your local shops to ask if they need an
assembler for the upcoming season. This is the lowest rung on the ladder at most bike shops. You're not expected to build wheels or know the arcane minutae of weird French 10-speeds from the '70s, you just have to be able to assemble and tune current-generation bikes. From there, if you show any sort of aptitude, you're likely to be assigned some repair jobs, as well as accessorizing new bikes that got sold, and as a backup sales guy.
And down the slippery slope you go
It's not a field I'd suggest going into, but that's your call.
