Hello sir/madam,
I've implemented some projects as you need (load pdf template, modified and saved it - without modified template). So it is easy for me to implement your requirement. I can make a demo and send a video to you or even I can show it to you via teamviewer. If you choose me, you don't need create any milestone, you can pay to me after I finish the project.
I would like to have a change working with you not only this project but also more projects in the future.
You can contact me via gmail: chithanh12[at]gmail or Skype: chithanh_12 we can discuss more about it.
Regards,
Chi Thanh
