The next step should be ?

So i have always loved the idea of tattoos and always liked the idea of tattooing about a year and a half ago i started reading all i could about tattooing I also also really started to pay attention to the tattoos i was getting and hanging out alot at my buddies shop. I was trying to learn all i could i recently decieded this i s what i want to do and after 6 months of my buddy trying to talk me out of it and letting me know how seriouse and hard this was he gave me a hand. I came to him with about 4000 bucks and told him i was going to do this so he rather than watch me waste the money helped point me in the right direction. I know have everything from an autoclave-therma fax 5 machines 2 backups an eikon power supply etc.. i have paid attention to keeping a sterile zone and not cross contaminating the area and the proper way to clean set up clean tattoo and clean some more. Now he told me he would help me get everything but i would have to work for everywhere i get in this industry and now im looking to find any more info i can on the tattoo machines them selfs how to build and tune them and also how to get an apprinticeship. any help from anyone would be most helpful Also my email is [email removed] if you could send anything
