Help me close more web design & smm clients

I’ve had a digital marketing agency for 4 years now and
I’m looking to increase cash flow
We’ve done roughly 30 websites and we’ve had 10+
retainer clients all who stayed on for 4-8 months some
who are still running
Our biggest issue is increasing cash flow so we can run
ads and payout more in commissions. Obviously to do
that we need to drive in some more clients.
I need people who can sell uncontrollably and aren’t
afraid of being commission based. It’s a eat what you kill
type of deal
I’ve had success in Facebook groups prospecting but
mainly the majority of business has come from referrals.
