Got an e-mail from the president of the agency today stating that this was "just for discussion purposes, but.."
Salary: 6 months at $5000/month, then $2500/month afterwards with renegotiation at month 18.
Commission: First 6 months, 0% unless GDC is $10k/month. After $10k of GDC, 50% of GDC but no salary. After 6 months, 50% GDC new business and 25% on renewal business. Plus, any "experienced" producer who helps close my business receives a 25% commission on new business for the first 18 months (this does not come out of my cut, the agency pays this.)
