278823 modify wp plugin

i have this plugin installed and need it modified and data from joomla's "mos directory" imported into it. i will need these features added: 1) addition of zipcode search 2) add some fields 3) add a group by category field with each category able to display only that category for example: only display the category "web hosts" if the link "web hosts" is clicked on 4) add ability to provide a link to a logo for each business with a fixed pixel dimension 100x50 and limited size 150kb from a web link only, if the image isnt found or is the wrong size then it isnt displayed
