Completing POS system

I have a POS system developed with php, mysql and jquery. Most of the work is already done, but I need some help as the deadline is approaching (Deadline is July 1st) Right now, what the system needs is: - Assign discounts to the check - Observations field (in case a client doesnt want onions on their burger, by example!) - Reservations - Add a new option on paymen, “Payment pending” (its just to add a new option, there's already all the payment system done) - Add persons name when they re going to use the payment pending. - Manual Counting up (a Report where they can see all the transactions made, again thats on the DB, we just need to make the report itself, It can be on php with html tables) - Choose a waiter when you select a new table. - Report of sales by waiter. Thats pretty much it. As you can see, is not that hard, I just need some help as the deadline is approaching, and I still have a lot of work with other clients. It would be great if you can have some communication with me via email and skype, as I need to know how's everything going or if you need some help or something. Thank you so much. Php, mysql and jquery is required. thank you!
