3d object compositor for indie film project

I have to modify a couple of cg shots by using maya with vray renderer. Looking for someone experienced in them. Here is the example of a close-up and medium wide shot footages I expected: [login to view URL] (also see the attached png for reference) I've already got maya project templates of the shots my cg specialist made before, the bird 3d object, and some 3d animations have been created. So you don't have to start from scratch and you can kinda reuse the animation, perhaps with a little modification to fit the new cg shots. I can color grade by myself and do the compositing in AE. In other words, I mainly need the exported 3d image sequence from Maya with different AA layers Please roughly estimate the price per shot in such a scenario (include/exclude the composting doing in AE, or just provide the maya & vray rendering). I should have to make 5-10 shots to do. Please feel free to ask if you are interested but need some more specific questions to estimate your charge. The budget can be re-estimated based on the workload variation.
