What (real)value do you bring to the vendor? I’m a florist. Very few “collabs” would lead to an order, an event, etc. I can’t pay rent on exposure but strategic collab *could* work.

Ask for some sort of partnership. Where you’re still paying them a fair (but discounted) price for their services, and they’ll get exposure. If they get a ton of exposure and sales b/c of your content, they may compensate you further afterwards! Also bring receipts of past successful partnerships to show how your content can help their business. Actual sales numbers from businesses from before and after they’ve gotten brand exposure from working with you.
