Buy ipad PDF editor source code

i want complete source code (objective-c) of PDF editor for iPad that supports, text, images, audio, annotations sharing, comments, stamp, sign, etc i need complete source code with out any limitation of license so i can use it in my multiple apps, i have already seen these libraries, PDFTOUCH SDK, PSPDFKIT, FOXIT EMBEDDED PDF, FASTPDFKIT, PDF READER CORE but again they provide limited license only for one app although they have good features. i want some one who have done same features for PDF editor for iPAD and if he want to sell the source code then contact me. i dont want any one to develop it from scratch i just want ready made code to be used thanks
