Grinder Pump Failure!

We purchased an 8 year old home this summer. We were unaware it had a Grinder Pump System until I started to smell sewage in our home last week, the alarm for the system was off. (Our home inspector didn’t know what the control panel with the light was, I have to give the guy a call) The system is a Hydromatic Simplex Suspended System, model # AHG-SPGA 200 M 2-2 Phase 1 Volts 230. Our home has 5 bath rooms and all waste pumps into the system. I also have 3 small children who love to flush the toliet.
I called my plumber out who said a paper towel and plastic applicator were stuck in it and the pump had burned up. He quoted me $1,600 to replace the pump. I took the pump to a commerical pump repair shop, who confirmed that the pump was a lost cause. He told me cost on the replacement Hydromatic Pump, HPG 200 M-2-2, would be $1050 and I would also need a new start relay, start capacitor, and run capacitor.
I have a few questions:
Should I replace the pump with only a Hydromatic pump? What brand of pumps are better quality, what brands should I stay away from? I know the rail system may have to be modified if a change the pump brand and one plumber I called wants to do this.
Should the tank be throughly cleaned out before a new pump is installed?
How long should a pump last?
Should I have yearly maintence done on this system?
How do I find a plumber/septic person I can trust to do this repair? These systems are not common in Indianapolis, and none of my neighbors have had theirs worked on yet.
Thanks for any assistance,
