Here’s a more concise version of your description for the Upwork job post:
I’ve developed an 80%-complete WordPress plugin called ‘Nearby Cities.’ It allows you to define a main city (e.g., Los Angeles), create a custom post type in Elementor, and use URL rewrites to generate pages for other cities based on a single template. The plugin dynamically replaces shortcodes like [location] with the city name. There are a few bugs and issues that need fixing to finalize the plugin.
What needs to be fixed?
* some bugs ([location] is replaced on page but sometimes a different city is displayed)
* implement cache system (each city page uses spintext and a random meta title/desc we dont want everytime someone presses f5 for the page to change we need cache)
* a few minor bugs
* we need some kind of simple licensing api so we can sell it as saas and validate user has active subscription)
