I agree with dv8 way to start out is to focus on the design, marketing and sales
A google search for contract screen printers should result in some contacts in your area
Contact then make sure tegu work on contract and will accept you as a new small but growing client, tour their site to get a feel for how things work, but don't pay them for the blank shirts just the printing
There are 5-10 large wholesalers from which you should be able to setup an account to but the blanks as long as you have a reseller id
From there you handle the design, sales, send the files and the blank shirts to the printer and they can drop ship to the end user
Can be quite profitable but takes time and is a very competitive market with risks involved
This way is much less risky than investing on your own equipment though
FYI: political clients, bars, restaurants, car dealers, radio stations prepay/credit card only
Those are they worst about paying so cover yourself with those types of accounts
