How to approach investor to be apart of their project?

[Nik Moushon]

I'm wondering what is the best and most professional way in approach another investor to try and convince them to let me be apart of their deal/project?

I know of a developer in my area that just (in the middle of) purchased a large track of land to develop. I know most developers would pass on this piece of property because it has a lot of up front risks but if you can get past those the rewards will be worth it. I don't have a large chunk of cash (I dont have some though) that I could use as a bargaining chip or decades of experience either. How do I initiate a conversation about buying into their project without getting laughed away and taken seriously? Obviously if they straight up don't want any other partners, no matter how much money I have, then I'm SOL. I don't want to come off as begging or this little fish that no one wants to notice either.
