Basic cash register.

I need someone to complete a basic cash register program Im writing in C. I've completed half the project myself, but Im off to holidays on Wednesday. Thus, requiring someone elses help to finish it off. Here's the project description: - Users must be able to enter product details which are written to a file. Each product should be identifiable by an ID, starting at 0 for the first product. (This part I completed!) - Product details must be updated (This part I also completed!) - Start a transaction (enter the amount of each product to be added to the transaction) and end the transaction (at which point the stock level is updated). (This part I started, but havent completed) - The details of each completed transaction should be stored in a sales file. - A receipt should be printed to a text file upon completion of a transaction. A sample program of the program is attached in a zip file ([login to view URL]). Note that the download includes two binary files which are used as the product and sales databases. To run the program you need to provide the names of both files at the command line e.g.: assignment_2 [login to view URL] [login to view URL] P.S. The C source code I've been working on is also attached (ass.c) Note: Im leaving for holidays on Wednesday, so priorities will go to bidders who require just 1 day to complete it...
