Ask HN: Lifestyle business question

I have an idea, which isn't particularly new. However, I know I can run it at a profit. There are some competitors, but the field isn't crowded and quality isn't great and demand is there. I've run the numbers and I can build an alternative which I can sell for ~50-100% less than the competitors, with better specs. I don't need to be #1 or #2 to generate a few thousand a month in profit with minimal effort to maintain. But here is the catch. I can do all the backend stuff, scaling, apis, dbs, automation etc. I have no frontend skills whatsoever and this needs a reasonably good UI/UX. What's the best way to go about this? Try to learn myself? Partner up with someone who knows UI/UX stuff? Can this be outsourced without necessarily sharing the details of the idea/backend?
