how to approach: pdf, fillin form vs HTML, workflow?

[squeaky]

Hello,
I am faced with figuring out how best to build a website based on the requirements below:

PHP & MYSQL

The entire process will be online.

The outcome will need to be an uneditable pdf document.

The document changes/denials/approvals will need to be tracked.

Person A will complete an online online/pdf form, consisting of approximately 75 questions. It will then be submitted for review.

Person B will review the answers, each question/answer will need to be approved – if not approved a ‘note’ with a reason for the disapproval will need to be offered.

The form will then get sent back to the Original Person A, where he will make the needed changes and the review process starts over again, until the document is completely approved.

Number 1 concern is workflow, I have never worked with any sort of workflow. Am I better off finding an open source s/w that handles workflow?

Second Concern is the pdf creation and management.

Do I use pdf fillin forms? Do I use an html form and generate the pdf on the fly, save it and allow Person B to only apply notes?


Any and all advice is welcome.
I am stumped right now on how to approach.
Thank you for your time.

Why a PDF needs to be created at all till the final document baffles me completely.

Thank you - That is why i am asking for suggestions.

My initial thought was to do everything in the db, and then when the final pdf is needed, generate it on the fly.

I was then informed that each of the 75+ questions, will need to be approved/denied.

My concern is an html form would then be required for the initial completion by Person A and subsequently for Person B to approve, or deny.

Having not worked with Adobe products much, and seeing that some will allow live updates and annotations. I thought this would be less cumbersome than a 75+ question form.
