You'd send the data to your server by utalizing jQuery POST like this:
var postData = $("#ContactInfo").serializeArray();
$.post('ajax/test.html', postData, function(returnData) {
console.log(returnData);
}, "json");
From http://api.jquery.com/jQuery.post/
Put the path to your server endpoint, that handles the posted data in replacement of ajax/test.html.
I did assume #ContactInfo is your form element.
I did use $.serializeArray() to create a sendable JSON of your form content, as you can see here http://api.jquery.com/serializeArray/
