Need to know a little more about the style you are going for, and also about your abilities to pull it off. That isn't being sarcastic, just need to know if you can do the welding and fab work, and have the equipment to do it. A proper welder is an absolute necessity (no little 110 volt box) as well as some means to jig up the frame while welding to keep in from pulling crooked.

Tell us as much detail about both subjects as you can and it will be easier to advise you.
