Need advice on a networking hosting plan for first game

Well met everyone.

I have read a lot of threads and sites on the networking plans, CCU, bandwidth etc.
My concern from all of this is that the game I plan on releasing some time towards the end of the 2018 will be a one time cost, and being my first game as a solo developer, I am not sitting on a lot of capital to fund the networking services other than what I generate in sales.
My game will not have IAP or a monthly subscription fee. I have been thinking of creating a server program that will simply host a list of available games to be joined and then have the clients connect to that and then be directed to the hosting client. The main concern for that approach is cheating (although I have thought of adding a <CHEATER> button that if flagged enough the player can be filtered out).

Any advice would be appreciated.
