Make an RTS multiplayer game online in Unity

We'd like an RTS (Real-Time Strategy) game built in Unity 5+. We have some asset packs that We'd like converted to the newest version so the assets can be used for initial implementation. We'd need the game fully coded for online multiplayer play, and the back-end server setup via Amazon. If a seller is selected we can provide more details around the project such as the requirements document and basic mock-ups. The game would need to include an in game store, global ranking for players, and maps made with Terrain asset packs we would provide. We would also like the games multiplayer to include 1v1, 2v2, 3v3, 4v4 teams. Looking for a general price range before committed additional details. Only apply for this project if you have had experience in RTS games previously, if you have never played/developed one please do not submit an offer.
