Opensource Unicenta oPOS modification. Java MYSQL Developer needed.

I'm using opensource Unicenta OPOS in a Cafe/Restaurant business. I have done little modifications myself to this program using Netbeans. But now I need a good Java programmer's help. I would like you to do the developments in Uniceta oPOS and you pass me the Netbeans project once everything is done. You will have to get the source from SOURCEFORGE. This project is going to be very difficult if you have no experience in Openbravo or Unicenta oPOS. I'm looking for someone who has done some modifications to this existing Unicenta oPOS opensource pos software. Once done, I need the source codes and you need to help me to compile it to verify things work properly. This is going to be a project that is ongoing developments. Initial Modifications needed: 1. Kitchen Display - I need a solution to have order display LCD to have all orders to go in to this screen displaying order information and time clock starts (Example, a Kitchen Order Display like in a fast food outlet or in a cafe's coffee maker). When order is finish making, the maker can tap on the screen to delete it (temporarily) and you can go back to deleted orders in case if you have delete it by mistake to bring the order back. 2. Receipt/Kitchen print out. Do not print only the attribute value if the menu or dish is not printed. I have some more features in mind. But just want to know these mods are possible and me how much each module is going to costs, I can communicate more on the other features.
