Need custom development to create JSON from SQL Query

I have an immediate project that I need help with. I purchased the plugin on here called Smart Search, a jquery auto-complete that pulls data from JSON.

I have a website that’s built in .NET, and uses MS SQL, and has a business directory, with multiple categories and businesses within those categories.

I need direct assistance with this plugin, help creating the proper query, and help implementing it. If anyone’s interested please let me know.
