Perhaps look for a more friendly school or club to operate from? Alternatively, attend any social functions at the club and become more familiar to them as a member. That way, when time is pushed people will be more inclined to help you get things going. I would never hesitate to help a hirer de-ice and fuel an aircraft, it's just common courtesy.
You could also ask for a double slot, stating that you will need the first slot to de-ice the aircraft if first thing in the morning. You are the customer here, if they want your business they should give you what you want.
If you can afford a share, it really is the cheapest way to fly. Especially if you get hold of a Permit to Fly aircraft, or soon to be Annex II, makes the maintenance a lot less hassle.
