Make my custom KODI Build able to be installed from zip on my Kodi.

I have been trying to setting up my own Kodi Wizard that will work with my own build and making it downloadable to my FireTV and FireTVStick inside the Kodi system settings by installing from zip file (in add on section). I have been working on it for 2 days with videos off youtube but nothing is working. My build is zipped and currently hosted on google/drive in a public shared folder. I have my wizard on my website but I continue getting errors when trying to install it on KODI. I am looking to hire someone to do the job? I have tried to do it myself but continuously, I keep get errors when I try to install the wizard from zips in add on settings. HELP!
