Hey Jorge!
I would really like to see the files and want to do a sample before coming to any sort of agreement in terms of budget and the turnaround time for this.
From what I understand, I see that you need to merge 700 files into 1 PDF, some are locked.
I try to figure out if there is any automation into this, but I need to really work on it first to get a hang of it completely.
I am guessing the coverages are a single file with 704 pages correct? And then there are 700 individual PDFs of product brochures. I didn't get the part what you said about the final deliverable.
Please open chat and we'll discuss this further, we need to talk in real time, I take a little time to understand things, but once I do, I make sure I complete the work with the best accuracy and detailing. I work individually here, so you'll get my personal attention into this too.
Here are some of my projects in PDF :

Here you'll find my portfolio : https://www.freelancer.com/u/sputnikbound?page=portfolio
And all my reviews : https://www.freelancer.com/u/sputnikbound#/reviews
Please note that I use Adobe Acrobat Pro, which comes bundled with forms central, if you need any help with that too, I can be of help there.
So let me know, would be happy to help, thank you.
