Create iPhone app tutorials

I need someone to create a iPhone app development tutorials for me. Something going through beginner level to advance level. for for example create an simple app for a beginner, this should all be a video tutorial, with english voice over explaining why you must do it etc. video tutorials must be high quality in hd and high quality descriptions. overall I'm looking for about 3/4 different applications to be made from beginner level to advance. so for example for the beginners app tutorial there would be roughly 10 videos, in the second video there will be a different app with more features making it slightly harder which would have around 10 videos and so on. to give an all round for the project I'm looking for someone to create iPhone application development videos for me, which will be placed on my learning website. after these videos are made they can't be sold to no one else or used anywhere else. around 3/4 different style apps to be created in video tutorials
