A lot depends on what they are investing in. Land, buildings, equipment etc. would be far different than an investment in an up and running distillery, especially one that has a proven track record and needs to expand.
I am looking for a start-up investor for my farm distillery and have found that if I had an existing set-up there are many willing investors from a few thousand to over a million. The more you have going the less you need to give away.
