Home Business Muse

i work for a marketing company, we market home security monitoring service. we are mostly college age students,im 22 years old. we move to a new state every summer from our home town and sell monitoring service door to door. we get about $500 per each sale.
its hard work but pays off, currently i signed with a new marketing company and accepted a $2500 sign on bonus, they said everything is the same as my previous company. now that its getting closer to summer i was just informed that we only get $215 upfront and the rest on our back end check. well. the thing is if we do certain things like not ask for a 99 doller activation fee we lose $100 off our commission and we lose money if we give out too much equipment. so all of a sudden that 215 becomes 75 or 100 a sale upfront. most reps quit before they get their back end with the rest of their commission. it states in their rep agreement that they dont get the rest if they quit. SOO i asked for more upfront at least 300 because thats what i was getting at my previous company, and after deductions i never saw the rest of my commissions. i had already accepted $2500 sign on oh and they are trying to make me sign my own lease so i cant leave in the summer. other companies corporate pays for housing and just deducts 100 a week from our paychecks but no obiligation if we need to leave. i can leave at any time and go to another company thats willing to pay me more upfront. but will lose business relationships and earn a bad reputation in the process. im 22, im a really good salesman i have being doing this job going on my 4th summer, i deserve to be paid all my money. if they dont give me more upfront should i just leave and go to another company thats willing to pay me more upfront??
