Thanks for all the replies and feedback. I think the more techs and personnel you have the easier it is to manage with a service, otherwise like @Old and Tired said, you can probably buy the uniforms and wash them on site. Like with everything else, have to pay for service. It's like having your lawn cut, someone will do it if you pay them, otherwise you can save money by buying a nice lawn mower and doing it yourself. However, there's a price to pay the time spent cutting your lawn or managing employee uniforms I suppose.
