Just a tip, I hope your contract with MFS is written very well, and that you don't get shafted, because if your not careful, you will. The care factor by their operators is pretty low as it is. Not saying it won't work, but just be careful, and I bet the filtering of calls won't be anything like it is now, I can see a lot of jobs that should be directed to Jim's Mowing being sent through.
So just make sure that contract is water tight and you think of any possibility, because if its not spelt out in large bold letters, it won't happen!!
