There's a shortage of construction labor now. You shouldn't have any problem finding work.
What is your end goal? Do you want to specialize in any particular trade, learn a bit of everything, or eventually becoming a general contractor?
Most homes are built by a variety of tradesmen. The grading, foundation, framing, roofing, electrical, plumbing, insulation, drywall, painting, flooring, trim guys, etc.
Most general contractors cordinate & hire the various crews, scheduling them in the order needed.
Framing is exciting because you're actually building the structure, but most guys quickly realize that most of the other crews get the luxury of working "indoors". Insulation & drywall aren't very desirable jobs, and neither is roofing.
Electrical, plumbing, and trim carpentry seem pay better than the other trades. Stone masons seem to get paid well, but it is hard work.
All the trades have plenty of beginner jobs. You shouldn't have any trouble finding a crew to hire you.
