Autodesk Inventor Drawing Revisions

We are a manufacturing company currently working on a project that requires us to design a pipe and duct system for an industrial plant. We have completed design drawings, submitted them to the customer, and they have indicated the changes they need on the drawings. Because of the time table of the project, and the fact that the changes are not related to the construction of the materials, we are fabricating the system, but need someone to go back and revise the drawings. Our engineers are all currently working on completing the design of the remainder of the system. We need someone who can work with Autodesk inventor files to revise them per the marked up drawings. It would involve some small changes to the BOMs, and putting drawing tags from the BOM onto the actual drawings.
