I'm impressed that you've had one hour free until now. Am I right in assuming that the money where you are is devolved to schools to buy in tuition? If so firstly find out how much this is, where I am this is under educational partnership money. The area manager of my local music told me how much mine was. I have one rate for group tuition and one rate for individual tuition and we charge £55 per term and run a standing order for parents who can't afford it in one go. I would contact some of the parents whose children have tuition and find out how much they are able to pay. Then do some maths and take it as a proposal to SLT. I negotiate my provision with the head and finance officer in a meeting and when I go with figures it makes it much easier. Will Birmingham support you in other ways? I can get free pyramid days for a days ensemble playing with my feeder primary schools for example as it benefits te music service if these pupils carry on from primary to secondary. As regards private peris, I use a mixture and monitor the quality myself, however this is great when they are reliable, however if you get into problems it can be a nightmare, as you have yo sort it rather than making a phone call. Have you got admin support for this? I couldn't run mine successfully without it. If you want any more details PM me as I don't really want to say more without giving away exactly where I am.
