Weird topic- Anything like an "angel investor" for student loans

[Account Closed]

This is a little off topic- but I have a question for anyone that may know. Is there anything like an angel investor for student loans or a way to locate cosigners that are out of the family? I have 140k in student loan debt and am working a sales job because I don't want to join the rat race in engineering (which I got my degree in). I am working sales since it is vital for my future real estate career and life goals. I have to refinance my student loans but I can't get approved without a cosigner and my parents absolutely WILL NOT help me with them. It is 100% out of the question. The thing that the student loan refinance companies don't take into consideration is anything more than salary. I have 3 drop shipping businesses that I've started in the last 4 months and have some very promising investments in crypto currencies that I believe will take off in Q3 of 2018. I have no doubt I will be a millionaire by the end of 2018 but that's not something that the loan companies account for and all they see is my small salary. Is there any other more personal option that could be used to get approved for refinancing? Someone that would account for these personal assets, or a cosigner that I could "rent" and pay like $50 a month to that would cosign my loans. I have to think something like that exists. I just can't find any information online for anything like it.
