Need some tech help with a passion project

Hey gang

I’m more of a drupal afficionado but I’ve started using WordPress lately.

I’m in the process of making a bit of a passion project and it requires some data to be submitted via forms (including autocomplete zipcode/postal code finder) and then based on submissions from hopefully other folks, use that data to map the results on google map.

I’m trying to use acf and I figured I can use custom functions and custom tables in the db to achieve what I need (and add Ajax calls and interactiveness) to the submission process.

However, I’m wondering if there is a combination of readymade plugins I can use. The site is trying to put together is with elementor free and it doesn’t support custom fields with acf free version( elementor paid version) support it, not free)

As you can tell, I’m trying to put this together with minimal or no purchases.

The end result is not meant to be commercial or for profit. But more informational, if I get enough data from general public.

Any criticism, thoughts and guidance from WordPress pros would be appreciated.

Thank you.
