Commission only telesales

We are an Internet mortgage broker with plenty of leads every day. We wish to expand the sales side on a share of fees basis. Fees are earned from client fees and lender commissions.
No specific mortgage experience is required as we will provide a scripted base to work from.
We have been operating since 1996 and despite the credit crunch still have adequate enquiries for a reasonable income. Expect around £300 per successful sale.
