Direct Mail Telephone Follow Up

I am doing a small direct mail campaign for my business. Letters are being sent to a specific target market and I require some follow ups done to book appointments for me. Either face to face or on the phone. I am initially offering a 5 hour trial @ £10 per hour with a £30 bonus for each appointment booked (payable once appointment confirmed by telephone/email. Candidate must be a native English speaker and able to work on specific days to fall in line with the post. He/she must also be able to use google sheets as we will share a document so that we can see in real time when you are on the phone/ doing the calls ( sorry if that sounds harsh but we’ve fallen foul of bad freelancers in the past!). Must have a professional phone manner and be willing to do a test call with myself prior to the campaign starting. If this works well we are happy to do this on a long term basis of 5-10 hours per week. We run a virtual PA/Telephone Answering Service business. So no hard sell needed. Full training will be given as we do this in-house and have a solid process - but we are too busy to use internal staff at the moment, so a long term freelancer joining our team would be amazing!
