Hi Mike,
I myself find that the majority of my business is local contract printing. When I first bought my machine I planned on making the majority of my money from my website, and found really quickly that the money was in local printing and doing multiples versus ones and twos. If you market yourself properly to local business you can do really well, especially if there are a lot of small business's in your area.
I will list a few things that have worked for me. I contacted local screen printing, embroidery and sign shops and let them know that if they had small orders that they could not print I would be happy to print them, and in return I would also send jobs that I was not capable of doing to them. It has built a great relationship

I also contacted local schools, churches, restaurants and many other small business's that might need shirts for events and such.
Its really funny because I didn't really purposely get into doing local work but it happened because there was a high demand where I live. I have now added a vinyl cutter to be able to do banners and decals and such. I will also use my cutter to do one color jobs on darks to save money on my costs

If you have any specific questions please feel free to ask, but I think your plan is a perfect situation for
dtg with looking at adding the local business to the Internet.
