Which social medium is better for these services

The Free For All Lounge

I wanted to offer services in big data consulting. I happened to post my services to facebook groups but those groups seem to be having a lot of spammers (as it is the case with the most of the social media communities )

Do you know groups , twitter handles where there are people active and really interested looking for the services ?

You’ll have hard time finding users interested in your services on FB. Have you considered LinkedIn?

not better than facebook, i will focus on it more
