Help, please. i can't find anything directly

Eventective.com and search for blank slate venues where you can bring in your own catering. Also look at the parks department venues.

A lot of venues will require you to reach out and speak with someone directly rather than just giving you a quote as pricing can vary depending on what you want and even time of year.

The vendor tabs on WW and The Knot are helpful. You can find vendors and send them messages directly through the app/website. A lot of them also show their rates on the vendor page.
