With a $1,000 budget, you probably aren't looking for my advice, but here's what I do:
I bought a set of 3 15" curved tire irons and use two pieces of 2x4 hinged on the wall as a bead breaker. I used a diluted soapy solution in a spray bottle as lube. It's a little manual, but very doable. I've replaced 5 motorcycle tires so far with this method (I think I could do it in about half an hour now). I don't do anything to balance them, but I'd consider using using Ride-On as a dynamic balancer if I felt any vibrations (I haven't so far). $35 bucks for the irons and they've paid for themselves many times over.
Same with you, I didn't want to spend the money at a garage getting them changed.
