What you're referring to is "in-kind investment" of "sweat equity", of a fashion. Basically, they both mean that the "investor" provides something to your business that isn't money per se, in return for a share of the company's equity. The short answer is yes. The long answer is dependent on some follow-up questions that I'd need answering before pointing you in the right direction. I think you need to put the brakes on and start at the beginning. What sort of funding have you already secured? e.g. friends and family, savings, co-founders, etc?
I would try IndieGoGo or JustGiving, or GoFundMe.
It depends. What's the current state of the busineses finances? More loans from where? Secured or unsecured? If secured, by what or whom? What is the company legal structure/format? In simple terms, loans will allow the business to increase the value of its equity without having to reduce your % ownership of the business by selling equity. I would need to know a lot more about your business to give a meaningful answer.
