Is it just me or are those some pricey Gi's? I saw more streetwear than I did workout gear which makes sense to help keep a brick & mortar store open. What is the population and density of Portland? That would surely be a big factor as well.
For fun, it did some research on what commercial embroidery and screen print machines cost. A common machine setup is 6 spool (colors). Then it comes down to speed and the level of interpolation (shape) you need. Ones that can embroider a school symbol like ours with minimal human intervention start at $110,000 and shoot up past $1,000,000. To my surprise, screen printing is a more step heavy process. There is a wide choice of software to produce the graphic. $100 to $5000. Of course someone has to know/learn how to use the software. A G-code interpreter. $100-$200. The screen making machine. $30,000 -$200,000. The application process. $25,000, totally manual, one color. $80,000 - $500,000 for different degrees of automation and number of colors. Then there is the square footage necessary for the equipment, added utility install and the labor to operate the machines. So it would take a lot of uniforms to see any kind of payback, let alone any profit.
