Good place to pitch for private investment?

Apologies for the likely newbie question, but my firm owns a suite of established and profitable online bitcoin casinos and sportsbooks. We are currently seeking to raise capital ($250,000 - $500,00) to grow our product set, as well as expand into B2B operations via reselling our existing proprietary software to other players looking to get into this sector.

We've posted on MergerNetwork, and are working directly with a broker-dealer in Canada to potentially execute a reverse merger on the CSE, but I'd like to look deeper into rich investment communities to share our pitch and private placement documentation with more folks to get more opportunities.

Any direction is helpful
