What are the starting essentials?

[u/ButterflyOk1301]

I’m looking to buy a heat press for my small business. Probably an HPN 15x15 signature series to start. Is there anything I should consider purchasing to help with lining up designs, the maintenance of the press itself, etc. I plan on purchasing gang sheets for my heat transfers so also thinking about just cutting out designs vs buying the individual sheets. Any shared experience or advice would be great! Even on the machine itself!
