Third Party PDF/TIFF Edit Control to go on Webpage

Greetings fellow Stack Overflow Contributors.

Client is asking for something very specific. They want their field engineers to be able to upload PDF files or TIFF images into a web page that we are putting together for them.

Subsequently, they would their field engineers to be able to perform some edit operations on the PDF/TIFF within the webpage.

I am seeking your input in case you are aware of such a third party control and provide an estimate on the price. I made my client aware that the ability to modify PDF such as PDF Distiller product is generally not free so they have a budget in for this control. Below is a summary of the capabilities they would like:

1. Tool bar contains icons and functionality for

   1. Single page view / thumbnail view
   2. Paging
   3. Zooming

2. Rotating Pages & Scale

   1. Can pan/rotate/resize/move an image that is not aligned correctly within the margins
   2. Format of tiff files stays the same
   3. Save changes

3. Applying Border Overlay

   1. Image will be displayed to the submitter with a border around it based on accurate border requirements for the state/county the image will be recorded in based on the margin requirements stored in the database
   2. A ruler representing inches is available and can be turned on/off

4. Erase Blemishes

   1. Able to erase blemishes
   2. Eraser tool is able to be sized to cover larger or smaller corrections
   3. Able to undo last step
   4. Able to cancel all work
   5. Able to save all work

5. Deskew

   1. Ability to correct a skewed image and save. Needs to work on both page and document level.

6. Undo/Reset

   1. Undo a change
   2. Reset all changes ->reload original image

I look forward to receiving all your feedback and anticipate that there are multiple controls that do the job here so what I have to do is research all and present my research as to pros/cons of each and of course cost which is always a factor.
