Blender video tutorial on demand

Hello, I need that someone make a specific blender tutorial for me. Infact I'm interested to learn how to : 1) importing a video containing animated characters to use as a guide to add a 3D object inside a video built with raster images 2) integrating a 3D face/head created with Facegen Modeller (it is good because it can make faces/heads taking a series of real faces/heads human pictures) and the rest of the bodies created with MakeHuman 3) characters created with Facegen Modeller and Make Human should overlap precisely the characters visible in the imported video on point 1 and this must be done with the deformation of the mesh and the Blender armatures and bones 4) every time the video go forward to one frame, the change must take place in real time so that I can deform the bones of the armature carefully and I can make a new keyframe 5) the imported video on point 1 should act as environment-background, as if it were a picture. Within it everything will remain the same than the original video except for the characters that have been recreated in 3D 6) giving the illusion that the new 3D characters are in tune with the rest of the original video 7) to make you better understand I give you some tutorials that do almost what I would like to do: [login to view URL] [login to view URL] [login to view URL] Thanks and Let me know...
