Format product pictures

I am working again on an ecommerce website and need images of products separated and cut our from their white background on photoshop. I will send you about 38 images. Most have multiple items ( some have 3 or 4 and some have 10 or 12). So in the end there will be about 200 individual images. And I will also send the psd for the background along with some items already in layers as example of size and what the final product should look like. I need the items perfectly cut off the white ( becoming transparent background) so it will go on a colorful background. They are relatively simple shapes ( bottle caps and some necklaces) You will send me ONE psd with all images stacked in layers with transparent background AND jpegs or pngs in white background with logo on corner, ready to be uploaded on website. Files transfers to be done using dropbox. and communication via email. Budget for this is $30 and I would like to get this done as soon as possible. In your bid pls let me know estimated delivery date, the sooner the better. Example files attached. * Send examples of your work.
