I have geodirectory installed on my site if you are fimilar with please do not bid I do not have the time to teach it to you
This a wp site
Delete the current data on the site, not the site just the data
the site has a search bar with this module you can have multiple search types
there is three differnt options on the search bar which uses this module [login to view URL]
The data is imported with wpimport
Then look at formating required to upload the data into those post ( search critera) You will have to add one column to have the data be sepearated for the search [login to view URL] is where you can see the search bar. then final you will upload the data.
this should not take someone more then 3 hours to complete 5 max their is no programing this is just using the modules
