working for equity instead of pay.

[Len Ayton]

Good day bigger pockets. I am a small business and I have been contacted by a large investor to provide a quote for providing and installing flooring in several of his units. I'm wondering is it possible to work for equity or a percentage of a deal or whatever instead of getting payed for work provided?
If so how should I approach him with the offer?
What should it look like?
what has worked for you in the past?

Any other suggestions that would be helpful would be appreciated.
