What exactly is it you’re trying to start?
I had my own business doing fencing and farm work and contracted myself out. I began with my two farm dogs and a few tools and as I made money I bought more tools and gear that would allow me to do more varied jobs.
I picked something that was in demand and easy to start at and I also already had the relevant skills.
People won’t invest unless you really know your business and target market well and you can really sell it to them. You need to get people excited if you expect them to part with their hard earned cash.
