You really should try to sell yourself a little better. This sort of announcement just shows you were too lazy to put thought into your service. Take some time and list the number of groups you have at your disposal, the number of friends/followers in each group, how many are active, and if any are in crypto.
You also should quote some sort of price and give a company a little room to negotiate with you if they show interest.
this would surely drive some interest. facebook is still a king social media network, someone who is good at it won't get hungry
But managing "many fb accounts" does not sound realistic. Facebook is a network to present yourself personal of your business, there is no proper simulation of authentic account. Posting to other fake accounts or reposting between them worth probably nothing.
From there, you can't expect something more serious because of the very low conversation rate. Promotion by one real influencer worth much more than 20 bot accounts.
