Thanks for the proposal! I've been impressed with Shreeda's writing at Meridian, as well as choice of coverage of on Byrne Hobart, Emmett Shear, and Dwarkesh Patel. I didn't know she was working on this dating site and think it's an important problem to tackle.
I agree that design is critical for a consumer-facing site like this; it's good that you also recognize this. Right now, as a user I would immediately bounce seeing this front page:

as the general UX design and the animal avatars don't inspire confidence, and communicates that this is very much in beta. I would go so far to posit that design is actually a key part of product here, and I'm a bit skeptical that hiring somebody external to help a bit would work (as opposed to having someone with design chops in the core team).
As a funder, I'd be a lot more excited to fund this if you had lined up a specific designer who wanted to work with y'all on this. $1k-$5k is a very small ask, so my main question is on whether you have the ability to identify someone with good taste, and can actually convince them to sign on.
Another major thing that's hard about dating apps is distribution (this is partly what we found with Manifold.love). If you had any kind of proof that you would be able to get distribution, that would bolster this proposal a lot. Even just like, running in person dating events before your website even works would be promising.
Finally, I think you need a clearer story about what tiny audience you can bring on as a beachhead. Famously, startup lore has it stated that it's better to have a thing that a few people like a lot, than a thing that a lot of people want a little. I think that Manifold Love's early targeting of rationalist/EAs was quite good, and that one thing that tanked it was trying to expand too fast with things like online ads -- it just diluted the applicant pool. A focus on serving a few users very very well is a lot more important.
