Create a tab for edditing the number of coupon sold and more

I have a daily deal website like Groupon. In the back end admin I create a new listing to display on the website and i want the option to edit the numebr of coupons sold. Let's say is 0 when I list it and i want to list it with 60. This will increase the credibility. Also in the right side of the website I have sponsored ads and it only show 3 items. I want to show at least 10. I have the option when I create the deal "side deal". If i check that box it will apear in the sponsored ads but it only work for 3. If i check 8 it shows only 3. I don't know why. The website platform is php and is a script from NDot .com I am willing to spend 30$ for this because I don't belive is a hard tash for someone who knows php and mysql Happy bidding
