In regards to the welding bit, just get someone in business say "Wooders garage" to put on two new apprentices, one evening a week at TAFE and you will both get subsidized from the gov. Go in as production engineers and you'll get all the training and knowledge you need, after 2yrs of that you can go for your structural engineer cert and your well on the way to engineering your own vechiles.
