Hi,
I can help you with the development of the game.
I created a large variety of different 2d projects for me and my clients and I can help with the development of a RTS.
I didn't know about this game you are inspired of, I did play a good amount of RTS back then, like Dune 2, Starcraft and others. Recently I moved to turn base system, because I want to have a more relaxed time when playing, so your idea for a relaxed RTS is quite interesting to me.
I am as well on the same page like you about how the games should be sold, in fact I am more for a pay once and own the game instead of subscriptions or other way to monetise.
I don't use Godot to create games, but instead Construct 3. You can find more about it here.
You can see some of my and clients' projects here:

Just to be clear, I do not work for revenue share, but if you are open to discussion feel free to get to me and maybe we can find an agreement.
Thank you.
