first welcome...the following is just my thoughts...do not take as legal of business recommendations!
My preference is to have my own heat press (can get a decent one for under $700) and press most of my own. To outsource overseas involves too much trouble with shipping, custom clearances, delays..etc.. you can outsource her by using some forum members...or others in your area, whether it is for transfers or screen printing or
DTG.
I am not aware of a way to duplicate transfers...what you see is what you get..a one time use transfer.. careful in redoing transfers..just be aware there may be some copyright or trademark issues
I think you can sell more shirts etc in a store than online BUT...you have to factor in the overhead...rent, util, insurance etc...in the end the more sales may not equal more net profit...certainly not at first.
Copyright laws are violated if you use copyright material whether it is online or in a store...
Yes there are places that will do custom transfers...search the forum for some of those places...
and last...I never ...let me repeat NEVER have items dropped shipped to my customers. I want to inspect the property first...making sure the quality is good and the transfers/imprints are correct...and then get to have face time with my customer to show I appreciate their business...
I am sure you will hear more....perhaps better...info from more experience members
