Convert 100's jpg images to png with transparent background

I need jpeg files converted into .png files with transparent background. The file name from the jpeg file should be retained with a new .png extension, i.e [login to view URL] should be converted to football1.png. I have 1000+ jpeg images that will need this conversion ASAP. Provider must knock out the background image of all JPGs provided so that only the actual figure is remaining then save as a PNG 24 bit Find attached a few sample images zipped. Convert these images to a transparent .png file as an example of your work and send the .png files back to me in an attachment along with your bid per image. Please provide time frame for work and a bid on per image price! Do not bid on entire job. Client must have individual price as bid, we may hire more than one provider to expedite process Maintain image size and save as 24 bit PNG and also save and send a 2nd copy of every image at a different height to be determined
