Im new to this site, but wanted to quick reply to your post. I have done a Groupon and it went great! What most people dont know is that you can negotiate with Groupon. They contacted me to set the first cleaning service up in my city I live in. I turned them down but they insisted. I then told them what percentage I needed to make it work. They agreed and we went along with it. I sold a total of a 1000 man hours (200 groupons) and have gained many customers from it. I do want to say though, you need to be ready. For one, ready to be on the phone for 3 days straight after the groupon is done, setting up appointments. You need to have enough equipment and supplies, and workers. Having contact management software and all your ducks in a row is a must! I had no idea the response I was going to get from that, but realized very quick that I had to have everything completely organized and ready. Its a great way for a new company to get their name out there and to add customers to your schedule. Just remember, NEGOTIATE! They do try to rip you off, but you can make it worth it in the long run. Just run your numbers, make sure that you know how much supplies you are going to need, how much for employee expenses, use of vehicle, etc.
