Point of Sale (POS) system for departmental store - URGENT

I urgently require a POS (Point of sale) system for a departmental store. I dont want you to code a new software for me, just need a ready S/W. The S/W should be able to handle all information related to products, sales, inventory, stock, return (return of sold items), employees & reports. Following are some important things I need to mention. Further if you have any questions PM me. I need to close this project in next 24 hours. 1. Each product is referred by a code like “PRF_345679 or 987678” so the POS system must accept Product_code to process sales information. 2. POS must be able to generate sales receipt in receipt printer. I have (EPSON TM-T88 II) 3. Main product of store are Kids garments, Gent garments, Ladies suites, Cosmetics, Pampers, etc 4. Purchase system must handle “purchase on credit”. 5. Security: different levels of access e.g only admin may see financial reports etc. 6. Reports: All sales, purchase, time based & financial reports. 7. I may have missed many things. Please discuss if you have anything on mind. I am short of time and budget therefore need some one to bid who has such a system ready and just want to resale a ready product. Happy bidding!
