How to search for broker dealers to help raise a $30M-$50M investment fund?

[Elliot Wagner]

We are operators with a $15M portfolio generating good returns over the past several years. We are looking to raise a $30-$50M investment fund to scale. We have spoken with some syndication/fund formation attorneys and are ready to prepare a PPM. However, we're unsure of how to search for broker dealers that can help raise the funds. Is there a database or a specific Google search I should be using?

We tried searching for "broker dealer mid market" and "broker dealer private placement" and got some hits that look like they could be a good fit, but not very many. Not sure if we're missing some obvious way of searching?
