I can provide assembly guidance for small projects you can do at home. Small assembly work not small group maybe. No harmful odors - gluing ,soldering. Requires a small investment for the supplies or parts and large table (kitchen or dining table). Need a screwdriver and small crescent wrench or socket. 2 jigs, 2 pieces of wood, tin foil and copies or print-outs is about all the parts. This isn't a job it's an opportunity to make something to sell. You buy the parts and keep or sell the finished product. I'm working on a battery as an example of one idea. A printer would be useful. Maybe end up with a group.
