$25M-$50M equity raise for existing rollup

Hello all, 18 months into our platform acquisition, our USA business has evolved from retailing 200 brands to serving as a 3PL/distribution/retail/liquidation partner for these brands. We have onboarded our whole executive team in the last 6 months, and now I feel confident we can scale. We are under LoI to grow the business from $25M to $50M in revenue in the next 12 months. At this point, we need much more capital than anticipated, seeking a minimum of $25M in equity, and could possibly get under the LoI for another $25M in revenue if we tried. Does anyone have a list of family offices interested in this? Would it be a good idea to hire a banker? Does anyone have more insight on this? Thanks, Marc
