Andrew,
I was raised by a single parent (mom) never had an interest in anything auto/mechanical until January 2000 when I got my first GMC; everything since then I've learned. I'm currently re-wiring my truck after an 11 year process. Had it in the paint booth when Katrina hit.
Here is my suggestion; join a local club or several for that matter, get to know the guys/gals -(there yes many gals in this hobby) and you'll be surprised that as you ask questions you will probably meet a member or two who has done exactly what you need help with.
When I'm stumped (as I have ben with wiring) I reach out to fellow BB members and club members. Example; I asked a local club member who wired his car to give me some pointers, NOT to do the work, but just be on hand to talk/BS while I did the work. 99% of the time they will end up helping you.
And as you get more into the hobby/passion/addition and have several items/techniques under YOUR belt you in turn will probably end up helping others.
A case in point: I can't paint a car BUT I can offer to sandblast parts for another member - remember ALL of us started just where you are for the most part. This hobby yfor the most part is one GIGANIC swap shop - whether it be parts/tool/ideas or labor. Think about why we are on this very BB - you asked a question.
