Auto Generate Webpages from a WordPress Sign-Up Form?

Hi All. I’m new here, so pls forgive my ignorance if I’m doing this incorrectly..!

I run a small live bands booking agency. I want to beef up my G00gle web rankings, and to do this, I HAVE TO generate MANY more pages for my website. To achieve this, I want a data capture form on the site, based on the exact layout of my current band pages, for all the new bands who approach me for representation, to be able to input all their details (I have one currently – Gravity Forms, but I’m not skilled enough to make it work, so I hope to delete it and use a solution from an expert here?). Then, when they click “SUBMIT”, I get a notification, so I check their form, and if it’s okay, or after I’ve made appropriate simple changes, I click “PUBLISH” to auto-upload it to a pre-determined “new bands” area on my site. There would probably be 20 or so questions they’d need to fill in on the form, so quite a few.

What’s the simple solution to this? There must be one in WP?

Many Thanks.
