At minimum not having done the hats makes it pretty hard to figure out a price. This is either total lack of business sense or just running a scam. Although crowding funding isn't without risk it forces the person to have a business plan and know what the costs will be and the people funding the project know what they will get.
Side note on the hats that drawing looks like it would work well for the ball caps and shirts with the photo image. Don't se it being done with embroidery.
