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
