Add a search field for couples to Dolphin 7 Boonex software

I am looking for someone who knows how to work with Boonex Dolpin 7. I need to add a search field for couples. Once that's done, I need someone to install a zip code mod that allows members to search by zip code and show the results in ascending order (i.e. someone that within 5 miles is shown first, then 6 miles next, etc.).
