I've been thinking for a while about running half-day SEO training courses as a method of gaining new clients and hiring a telesales company to sell the tickets. Looking on Eventbrite, there are quite a few people running half-day courses for £50 each and they are all offering really basic stuff. I figured if I ran courses for 20 people and sold the tickets for £50, it would be a good way of getting in front of potential clients and hopefully making a bit of money at the same time to cover my time putting the course together and delivering it. This sounds great in theory but the problem is hiring a telesales company. I have spoken to a couple of telesales firms and the best one wants to charge £300 per day and has said they will make 100 calls in a day. They say they have sold SEO training courses before and sold 15 tickets at a similar price in 1 day and filled the course so reckoned that £500 would easily cover it. 15% conversion rate sounds too high to me though and I reckon they are more likely to convert 1 in 20. In which case i would run at a loss. Obviously it does depend on the quality of the list and the person calling but what is a reasonable conversion rate to expect do you think?
