The estimated cost per implant 80k to 90k year 2025  if there  a need for bone graft is 25k..... number of hours will be spent on the procedure maximum 2hours... thats the 1st stage.. 
let the implant/s and bone heal for about 9-12 months for best results to minimize failure... 
2nd stage takes 2weeks. until you have your crowns. 
hope i answer your inquiries.... 
but first we need an xray to diagnose...
