Partnering in Deals - I do the work while my partner puts most of the cash

[S L]

Sorry if this question is repeated in the forum. I'm a first time investor who's looking to buy and flip.

I have a partner who is willing to put up cash (75% of the deal) and his role is basically as a financier while I do the work(finding the property and managing contractors).

So for example
100k house = 25k mine, 75k his
But I do almost all the work

1. How would I structure this contract for the profits?
-25%/75% (mine/his)
-35/65
-50/50

2. And would this be the same structure for the losses?

3. Any other tips that would be good to add?

Confused but optimistic,
-S
