Store Locator Pagination Issue in Search Functionality.

We are in a requirement to implement search functionality along with paging for store locator.
We have thousands of stores and the search result is large enough to display on a single page for that purpose we need paging to be implemented.

We are using getPage Add-On to display paging for store locator, we need to first get all stores then filter results to find nearest location and then get the result collection pagination. We have managed to filter the results into array and converted into collection but seems the collection is not building correctly.

We have used getPage call twice on the page, i am not sure if that could be a problem.
I am open to all solution, i have tried one solution without using getPage but that also does not seem to work.

Please let me know if anyone have solved this sort of issue.
