PDF watermarking Project (Online)

Hi, I cannot provide all details publicly. In short, you need to develop PDF (acobat PDF's) stamping/watermarking script online (that dynamically watermark PDF files with buyer's information when order is placed using 'some' sites). Project is Easy and should be done fast. CONDITIONS: 1) 10% Escrow on selection, 10% when you show the work, 80% escrow and release on completing work. 2) Feedback should not be LESS then 9.5 3) Minimum 10 feed backs needed. 4) Maximum of 7-10 days can be given for execution as it's online script that do limited things on fly. 5) If you complete project in 3-4 days, i'll reward you with 5% extra from your bid. Please note: I got 100% positive feedback as "projects provider" so you can expect instant payments (as mentioned above) and in return i expect instant work. DO NOT bid if you do not work on weekends, holidays or other 'offs'. If you expect that your some relative will be ill or your leg can break or you need to admit in hospital. We all know 99% of time these all are lame excuses, so i won't tolerate anything and i have cleared that.
