Coingecko has a strong warning for people who are offering to expedite listing on their platform
Anyone claiming that they can list a coin or expedite the listing process on CoinGecko is a scammer.
You are asking for a huge fee without showing us anything, for us asking money without showing proof of their work is considered attempted scamming, I don't know how are you going to address this when Coingecko issued a strong warning and they have not changed their policy until now.

Any project development team that pays for such service just to get listed on Cmc or CoinGecko don't even worth having a project in the crypto market.
