Bro I hate to tell you this bur in LL you get what you paid, tibias are expensiver than femurs, the best is to save and go for a respetable doctor.. there is no cheap concept in LL is like having a cheap broken ferrari.. you could but you should not at the end is you life and your healt.. thats the problem of LL
No, this 'you get what you pay for' BS is what american doctors charging 2-3x the rest of the world want you to think.
Sure there's some bad outcomes elsewhere but if you pick someone decent (i.e. not a turk butcher) and have reasonable lengthening goals and give yourself time to do it, there's no reason you can't have a good outcome paying less.
Vietnam as mentioned is a good option for LON for $20k and there's been a few good diaries from there. If you want femurs/internal nails then Greece is an option for $45k. There's no need whatsoever to be making a $100k donation to Paley cos 'you get what you pay for'.
