Maby contact these guys: https://wlan-si.net/en/ https://wlan-si.net/en/ They are(were) deploying wifi mesh networks on the cheap in Slovenia. They've covered entire towns that did not have internet access in the past (mesh network in the town + string of directed antenna to get an uplink from a bigger town). Routers they used cost in the range of 15€ each, but the last time I talked to them they had trouble supplying new routers.
