Data Entry Task

I have a text file which needs to be completed by duplicating chunks of the file, and then numbering each duplication. There are 54 'categories' in the file at the moment, each of which needs to be duplicated (copy and pasted) a number of times (between 20-150 times) depending on the category. Once each category has been duplicated, each duplication needs to be numbered... 1,2,3 etc. Once accepted, I will send you the file and provide more details - as to what needs copying, where to add the numbering, and how many times for each category. This can also be discussed on MSN/ $30 is the most I will pay for this job, and I need it completed within the next few hours (asap). Thanks.
