514368 Photoshop: Separate the background from the images

Hi, I am building a clothing catalogue website. I have a fairly simple and routine job for most web designers. I have 37 photos in which I basically want to place the model on a transparent background. Requirement: I will give 37 .jpeg files. For each of them I need to you to get rid of the background and only extract the model (taking care of edges, etc). It needs to be done well. As a delivery I would like the new .jpg images with transparent/blank background and also the corresponding .psd (photoshop) files for each of the image. I have attached a sample image. Please indicate when you could finish the project. I would like the delivery by Thursday 4th August as I intend to work on it over next weekend. I am a developer and graphic design stuff is not my thing. You can see this as a trial as well. There will be more future small work like this one relating to photoshop work.
