Hi, this is Pavel here.
4 years of LoRa/LoRaWAN experience. You may see a couple of related project on my profile here.
Can you please provide a bit more details on your needs/requirements? Installing ChirpStack server is pretty easy and quick task, not sure what prevents you from installing it on your own. Do you also need to properly configure it/configure gateways and devices/etc.?
Thanks,
WBW,
Pavel.
