Unfortunately, i had a friend who opened up something similar...but it eventually failed. From what I have seen, the profit you make out of this is minimal - just okay however, not enough to satisfy someone who is going to invest a large capital sum and a lot of time into the venture. Dealing with parents, kids and workers is not easy. However, i will finish by saying that if you love this business and would not trade it in for the world..then go for it! I admire you so much because this is not an easy job. Anyway, an in-door football space or a footpool would be a great option! My daughter loves the one at her daycare place, plus it suits a wide range of ages. Keep us updated dearie
