This site has been a wealth of information for months so I am hopeful I can find some help/leads here. I'm looking for your recommendation for funding sources.

I've been in ongoing talks with 30+ businesses for about a year now. All at various paces, but it looks like a combination of factors may make 4-6 happen in a relatively short amount of time. The target is 50 acquisitions by the end of 2022 or sooner.
These are all in the insurance business and all being bought at very attractive terms. But, although the owners holding a note is still possible, several will benefit from larger up front payments.
I'm looking for your recommendations and suggestions on institutions that would lend or leave a credit line available from $500,00-$1,200,000. I'm also open to convertible notes and other creative options.
