Sponsoring my Game

So I’ve been making my game for a couple of days, everything is planned and the game is almost done. The last part would be sponsoring the game (promoting obby on a social media imo wouldn’t be very effective), but I have a very low budget of 1800 robux and I’m getting very low amounts of them everyday (around 5-8 robux per day).
Is there any way to promote the game, at least with this amount? Also, I don’t really want to go bankrupt and be left with nothing in the end with no possible way to promote a game if I fail to do so with 1800 robux. Any tips?

Just found out that you can sponsor the game only with minimum of 2850 robux, so I guess I’ll have to wait?
