I know someone who owns a fairly large medical tourism company. If you have a steady flow of paying clients, he might be interested in investing or some sort of partnership.
If you meant that you're interested in increasing the amount of clients that you have, then I'm happy to give you some pointers, but I would need a lot more information. I'm happy to give you a free 15 min call to get the info, and then we can schedule a second call during which I will give you my advice.
I've successfully helped over 300 entrepreneurs, and I'd be happy to try and assist.
Good luck
