Sorry no plasma, laser or waterjet where I work. We mainly do stuff out of bar stock and the way we do plate material is less than efficient. The cost shouldn't be too bad getting it cut on a plasma table or even a waterjet for that matter. The brackets shouldn't be too complex to cut out and not that much material. Finding the right shop they could probably also do the bending on a decent brake.
On your design, do you think you are going to have any problems with the torque from the motor? I would imagine that the wheel axles will have to be pretty solidly mounted. What are you going to be running for gearing from the motor to the crank? I work through spreadsheets figuring how much crank speed and torque I can get but in the end they are just a bunch of numbers and don't mean that much, guess it's been too long since I've had a decent physics class. Are you going to put a freewheel on the motor hub or just use the freewheeling action of the motor as the freewheel?
A Tig welder is on my wishlist but for a good one that can do aluminum is pretty spendy. I think there are quite a few people who don't realize what an art Tig welding can be. I did a little in high school but then it's been mainly stick and Mig from there. Keep up the good work.
