Indeed I would reconsider the difficulty rating...
Been there, did the fix myself with a kit. It is a lot of work, much more than I had anticipated.
If your on Renntech I sort-of took over another thread about a top, there are a couple pics there as well as some discussion of the process:

If you are
not a hardcore DIYer and do not have someone to help you with the stitching I would recommend you find a shop willing to stitch in a new window with the canvas still on the frame. The entire convertible top (canvas & frame) is surprisingly easy to remove. Most shops want to remove the canvas from the frame, that is where it gets expensive.
Also see this thread where we touched on the subject:
