Hello from Wisconsin! Seeking guidance!

Hello everyone!
Just started scrapping recently, also I'm very young. I have a lot of questions so bare with me. I have been breaking down metal/shadowing my girlfriends dad (who is a experienced scrapper) since the start of this year. Only downside is he does it part time and on his own time. I've caught on very fast and now I'm hooked but have never brought a load in myself only with him. In my area I really think I would have a good chance of making incredible profit if I started a metal recycling "business" /make business cards saying metal recycling including appliances (list), junk removal, etc. I have a lot of good connections I could give the cards due to friendships but I'm seeking some tips, guidance, and your experiences before I start. I am very serious about this and would love to hear some feedback! I'm hesitant on handing out the cards until I feel STABLE with what I'm doing because he is the one with the truck and trailer. He did say he would work with me but I don't feel he understands how into this I really am and I don't want to burden him with all the driving (saving up for my own truck). In this month alone I've had thousands of lbs of metal lined up for pickup but have backed out on telling him because I feel like a burden having him drive all over for me. Where should I go from here? What's a great cheaper starter truck? I have the will power, determination, and a lot of resources just need the guidance. Thank you all so much and god bless.
