I am creating a WordPress site that let users:
Create ads: each user has a spanish postal code on profile page that gives location to all his ads
Search ads: users can enter a postal code to filter results by distance from that input postal code to ad’s postal code. Showing near ones first
I have a database with latitude/longitude for each postal code, and my project do not have big economy, so I am afraid of having good results and die because route costs.
I am the founder and designer, without backend programmer yet, so I don’t understand good the documentation, sorry about that,
I need to know what free options I can choose to provide that service, forgeting about number of distance requests
Thanks for your time,
