Call contractors in Denver/Boulder area and sign them up as vendors

We are a local provider of household services like: plumbing, electrical, lawn-care, painting etc. We are signing up vendors in Denver/Boulder area to call different contractors and sign them up as our vendors. So that when we get customers, we can send it to them. I have the script to talk and also a database of vendors to call. Also want to build a long-term relation for getting someone who can talk good US english for front-desk phone support (calling for appointment confirmations, reminders etc). I am looking for 20 hours per week to start with and it can increase later as needed.
