Startup wisp

starting a new wisp building on multiple towers in SE Ohio hilly country. initially trying to hit roughly 250 customers hoping to provide 25-50 mbps starting with 1 gig back haul that can be scaled as needed. first deployment will on a water tower i will need to deploy APs to use as repeaters was looking at the 450m for the tower and 450i as repeaters’ is that a good solution? what are your thoughts?
