PHP/JSON-jquery pagination

I Need away to show two per page, and have a pagination at the bottom of the page.

Here is how I am currently doing it.

As you can see we dont do any pagination at the moment.

PHP code which returns the JSON data

public function realcashoffers($state,$count)

{

 $this->state = $state;

 $this->number = $count;         

 $result = $this->JSONselect("approved_business, business_stores, Real_Cash_Offers"," *, group_concat(offer ORDER BY offer ASC SEPARATOR ',') as offers"," approved_business.id = business_stores.business_id AND  Real_Cash_Offers.business_id = approved_business.id  AND Real_Cash_Offers.storeid = business_stores.storeid AND business_stores.state = '{$this->state}'","GROUP BY id ORDER BY RAND(), approved_business.id DESC LIMIT {$this->number} ");



 $remaining = $count - count($result);



 if ($remaining) {

    $this->type = 'G';

    $result = array_merge($result, $this->JSONselect("iNcard_Products","*, productname as tradingname, CONCAT_WS('|', id,'{$this->type}') AS id, CONCAT_WS('|', spend, cashback) AS offer, group_concat(CONCAT_WS('|', spend, cashback) ORDER BY spend ASC SEPARATOR ',') as offers ,picurl as pictureurl","picurl != 'NULL'","GROUP BY productname ORDER BY RAND() LIMIT {$remaining} "));



 }



 print $this->JSONprint($result);

}

The the jQuery Code

function fetch(e,formstring)

{

    var a = 1;

    var b = 1;

    var rc="";

    var spendoffer="";

    $.ajax({

      type: 'POST',

      url: 'http://www.incard.com.au/newsite/system/classes/core.php',

      data: formstring,

      dataType: 'json',

      contentType: "application/x-www-form-urlencoded;charset=utf-8",

      beforeSend: function() {

                switch (e) {

                },

      success: function(data){

        $.each(data, function(i, obj) {



               switch (e) { 





                 //300 OFFERS

                 case 300:

                 if(a != 9)

                 {

                 $("#title"+a).html(obj.tradingname.toUpperCase());

                 if(!obj.discription)

                    {

                        obj.discription = 'We make sure that all of our customers leave with what they expected and are happy.';

                    }



                 if(!obj.pictureurl)

                 {

                    obj.pictureurl = 'http://www.incard.com.au/newsite/template/categoryimages/iStock_000008235598Small.jpg';

                 }

                 $("#pic"+a).html("<img style='width:180px;' src='"+obj.pictureurl+"'/>");

                    b++;
