Need help building an app (I will not promote)

Hi all! I wanted to gain some insight from the minds in this sub. To start out, I wanted to tell you all that I am not a technical mind. I have done any technical work in the past. My background is 25+ years in sales, biz dev, marketing, CS, etc. However, in the last week or so I've attempted to build an app by using Cursor AI and other AI tools. But I'm beginning to hit a roadblock with connecting databases/the back end to the front end. If I don't pursue building the app myself what's the best way to source efficient work/contract work for a web app? this would be a B2B web app in a focused industry primarily targeting sales and customer facing professionals. Thanks for any input! (I will note promote)
