A2billing Agent UI development

For Asterisk2Billing software , some development for the Agent UI 1)under Customers category: -Create "Easy Create" This subpage will be responsible to easily create a customer account: Ask for "First Name,"Last Name","Phone Number" ,a drop list to select "callplan" and button "Create!" It should be able to create a new customer that will belong to the specific agent's customer group like a2billing does(new customer on mysql table with unique id) Caution ,we first create account and then assign a callerid on callerid table for that customer ,the field "phone number" we got from the user input (so customer can call and can get automatically authenticated on pinless calling card) It will return message : Success ,or Error if the customer already exists(if the specific callerid exists on callerid table for any customer) 2) Under "Customers" again: -Create "Easy Recharge": A subpage that will ask "CallerID" and "amount" and button "Recharge!" It will send a query to search the callerid table ,if no match to give error If the amount of credit going to recharge is more than what agent has available give error If callerid match to customer ,then we go on customer table locate the customer and update the balance ,for example +$5 The same time deduct the -5 from agent balance(on agents table in database) and additionally make a calculation for the commission of the agent(ie 20% exist on the agent's configuration) $5*0.2=$1 ,it will add this $1 to agent balance this has to be logged on transactions of a2billing in logrefill table I need somebody with experience on a2billing development
