It sounds like you are going after high value targets who have layers and layers of insulation between your company and decision makers. If it were me, I would find someone either on here or on Linkedin who have existing relationships in your core industries and work out compensation deals with them directly. Everyone is different with how they want to be compensated, however, since you have self-funded, any revenue is good revenue at this point. I have some ideas for you if you want to contact me directly.
