That was a big problem for me back when I expanded my operations. I used my church as a resource to find good part time help. There were a number of young men and teenagers who I hired from the youth dept. and the college Sunday School depts. They worked out very well. Especially the guys from the college age group. Those guys could often work even when college was in session, as they had days with few, or no classes. The high scholl guys were limited to summer vacation time, and sometimes weekends when school started in the fall. most of the college guys I hired attended one of our local colleges, so that helped with availability.
