Need advice on first purchases for start up
I'm tired of working 16 hr day for some one else. I am unemployed for the first time in my life and I'm 27. I found a passion in repairing phones and tablets after I had to learn to repair my son's ipad air 2 because I could not afford what a shop wanted to do the job. I have always had a good work ethic and Its time to build something with it that will last and I can pass down to my children.
I'm trying very hard with side and odd jobs to save enough money to purchase a couple machines like a LCD seperator and bubble remover to make myself profitable in the repair business. What all do I need to make sure it's done 100% to ifixit standards and is there any were you recommend to buy used machines for a guy that cannot get loan because of mistakes I made when I was younger
