Looking for a consultant to help setup HA w/ Google Home and other integrations

Overview:
Need help setting up Home Assistant on raspberry pi and integrating it, happy to pay an expert to assist.

Primary technologies:
Google Home, Harmony Hub + Remote, Nvidia Shield, Home Assistant

Desired Voice commands:
Watch TV - turn on Denon receiver and LG TV, set to correct input, turn on Nvidia Shield, set sound to Dolby Digital Surround with channel volumes at standard level

Play VR - turn on Denon receiver and LG TV, change input to pc, start steam VR

Play my music - play songs randomly from my apple library on shield with 5 channel surround enabled, volume down on rear speakers, and ideally start Project M music visualizations too

control these via quickselect voice commands (optional if possible):
Change center spread - enable/disable center spread
5 channel surround - change to 5 channel surround
Rebalance Music - bring down volume of rear channels

Devices:

Nvidia Shield - used for all media playback on LGTV

Harmony Hub - Integrates with Google Home

LG TV - Everything is on single input

Denon H750 - Home Assistant should be able to control this

Smart Lights - I have hue’s setup with routines in the hue app and their hub, does it make sense to move some of that to HA?

Computer - Used for VR, I have eventghost installed to run webhooks. Eventghost.net - I have trouble with the syntax of scripting the pc automations, maybe there’s a better solution? Join and tasker maybe?

Physical Controls - It’d be nice to be able to assign some of the voice actions to buttons on the harmony or shield remote - I’m not sure if that’s possible. Buttonmapper looked like one solution. Maybe bluetooth buttons or something similar could be a solution.

Hi welcome to the community

And then Google changes their API and your setup no longer works and you have no clue how it works :upside_down_face:

I suggest starting small, one thing after another, read the respective documentation, try it and once you are stuck or something doesn’t work you can come here and ask for help again, posting your code and we may be able to assist you.
