I suggest starting with ink jet and moving on to sublimation later. The ink jet will get your feet wet and make you some needed cash to invest in other types of services. I would start with a c120 Epson and the
JPSS paper for light garments and the Jet wear for dark garments. I suggest the c120 because the cost is lower and you can do a lot with it. As time goes on you can expand to another printer and then use the c120 foe sublimation. If you don't have a heat press ,I suggest a 15x15 (minimum size) and a name brand for ease of customer service. Good luck and happy pressing. .... JB
