Where to start with heat presses?

[Dagema]

Hi there.

My new business is going to need to be able to apply graphics to mugs and T-shirts as well as pens and usb sticks. I am aware of the type of presses used for mugs and t-shirts, but don't really know where to start with working out the type/brand/size that I need.

I really don't have a clue how to go about applying graphics to usb sticks and pens though, so if anyone has any information they could share with me on that subject it would be most appreciated!

Thanks you all again for your time,

Da
