<font face='Comic Sans MS'>You might consider doing it yourself. I've done many over the years with complete success. No need to split the caliper halves to do a rebuild, but do eyeball the pistons closely for pitting etc. Replace if in doubt of their condition.
As far as silicon fuild, I've been running it in my Hipo for over 10 years now. Absolutely no issues. Some may claim a softer pedal with the silicon fluid, but I can't tell if there is a difference. Bubbling has also been mentioned by some, primarily when bleeding the system. That could be so. After about 5 yrs on the road, when preping the car for the 40th trip to Nashville I did a system bleed just for S&G, and did get a tad of air from the rt rear caliper. No way of knowing if it was a left over from my original system bleed, or ?????? I think silicon is the way to go for two reasons; It won't destroy paint and most importantly it is not hydroscopic.</font id='Comic Sans MS'>
