Where do you find private investors? i dont mean angel investors because i dont understand online stuff. Just someone i can call and pitch?

Other answer:

Careful…. there are laws about soliciting investments in unregistered securities.
How much money are you looking for? The lower the amount, the easier the process. The reason most rich people are rich is because they are VERY CAREFUL with their money.

Nominal amounts, start with friends and family AND people they know but you don't.

Larger amounts, your IDEAS or GUARANTEES are much more important.

Good luck!

you ask, you talk to bankers, investment houses, friends, neighbors, etc.
You can advertise in the newspaper
