Hi we are new to hubitat and looking to hire a programmer that can setup a residence with z-wave devices (Zooz switches), nest and echo hubs.
While it's possible someone in the community here would be willing to pick this job up, the main reason this kind of transaction is very rare is because it's inherently not a one-time setup job... Disparate home-automation systems (like Hubitat, Home Assistant, SmartThings) require a not-insignificant amount of ongoing care & feeding, and that very quickly becomes a difficult support issue for both parties to navigate.
Closed systems like Control4 etc are easier for both parties to manage in that respect, but you pay ($$) heftily for that convenience.
For the vast majority of Hubitat, Home Assistant, SmartThings etc users, building & maintaining our home's automation is an ongoing hobby -- since we all enjoy tinkering, it's usually a fun hobby but it can be downright maddening when things go awry.
You probably should indicate the range of your budget, and the anticipated services.
In the absence of this information, community members who do offer such services cannot gauge whether the services they offer will match your expectations for the indicated price points.
