PDF/Word documents altered

Hello! I have a few PDF files that need to be edited / changed. * 2 contracts (2 pages each, currently in PDF) need to be combined into one contract ( I will send changes -- they are easy and will result in one 2-page contract only). Also, I need the PDF converted into a Word document also, and made easy to manipulate so that I can make further changes later and then convert back to PDF. Currently, when I do that, the formatting gets messed up. This document will need to be reformatted probably. (double-sided, small print contract) * I have a letter and a flier that I send out to prospects (both PDF currently). I would like to combine them into one PDF and be able to insert the name of the prospect into a field (i.e. space on the page) and save the combined letter/flier as though there is NO changeable field. I can be more articulate if I show the winning bidder how the PDF flier was made originally, and my steps to save in this manner. It is not complicated. FYI, I have Adobe 9.0 on my computer. I really don't have the time/patience to tackle this job, but should be perfect and pretty easy for someone expert in Adobe/Word. I will clearly explain all needed to be done! I will have lots of smaller jobs from time to time for the right relationship! thx!
