As you can see, per submitted review the certified user can set mutiple FB and Twitter urls where it';s shared. The points are "coins" which are collected. The grand total of all points (you can set the value later) are the same value as dollars. Then i set a Paypal button with the amount so you can sent out the "donation" in 1 click to the submitter, Checkbox setting that this sheet is "paid" and done. The user will see a complete list of all "work done" and "transactions"
