How to get your new film production company's name off the ground?

This is sort of a hypothetical question but here it goes. Let’s say my friend and I have an awesome screenplay written. And we got it into a production company exec who loves it; the company wants to buy and make it, period. Now let’s also say that my friend and I have a production company of our own. However, our company really only consists of a licensed name and very small company bank account because it’s brand new (no real money or contacts). How do we go about dealing with this other production company, and make ourselves partners on the project (aka getting our company name on as a co-producer and what not) and even possibly being development producers on it. I know it’s a lot to hope for, but I dream big. So any ideas on how to go about something like this. Any advice is appreciated. Thanks!
