34 Local Dealership worker needs temp place to stay (Burlington and it's surrounding areas)

I'm a student and dealerhip technician.
I need a place to crash for the next few weeks.
No point in spending my last few paychecks on a hotel or lease.
I work as a mechanic in the area around Cambridge/Watertown.
I'm offering $100 a week.
I'm terribly embarrassed this as much as I can offer rn.
I'm transferring to a dealership in Nevada.
Any help with a safe place to crash near my job while I'm finishing up my last 2-3 weeks here would be greatly appreciated.
I have a car, my own toiletries, blankets and sleeping bag.
I leave early in the morning for work and come back in the evening.
Non smoker, I have no pets this is just for myself.
I can also possibly help with basic Automotive repairs/diag as I have my own tools.
Please call/text if you have a space I can pay you for.
