What would be a reasonable percentage to ask for?

I’ve always had a talent for making ice cream. As of late ive been poor, so it got me thinking selling my ice cream would be a great way to make some extra cash.

My problem is I really have no clue how the hell do even go about doing that.

My one idea is to go to a newly opened ice cream place down the street and propose the idea of doing like a flavor of the week for them. So I’d just come in once a week and make a big batch of whatever flavor for that week.

I would think asking for a percentage of sales off of said flavor would work out best for both parties.

Thing is, I am horrible at haggling so id rather just cut straight to it. What would be a reasonable percentage to ask?

I hate saying it cause i sound like i bragging about it, but to give everyone an idea, the last batch of ice cream I made was pineapple ice cream with caramelized pineapple/syrup swirled in.

The syrup the pineapples were cooked in was honey,butter, brown sugar, cinnamon, nutmeg, cloves, and vanilla.

Only thing i have to change is next time add graham crackers. mmmmmm

Adversely if anyone has any other ideas that would work for me, im all ears :)
