If you do decide to string, and string other players racquets, then I advise to get as much machine as you can afford. I would at the least get fixed clamps, a 6 point mounting, and a good brake system as a minimum.
It would make the job easier, especially if stringing a decent # of racquets, the more features the more enjoyable it is. Since you are in an area where there is no competition, you should have no issues getting a decent buisness. Just be sure you have a good technique down before you start on other players racquets. You would not want even one racquet to leave your place with any mistakes or issues.The USRSA has a decent manual called "Racquet Service Techniques" that has just about all the basics needed for stringing. Also some very well put together videos on this site.
