Logo image edit & clean up a few product images in photoshop

We have our logo already, however, we need it to be cleaned up to look more professional, it looks a little bit incomplete. I also need the logo to be made in to monochrome version. Needs to be high def and in various sizes ready for print and online publishing. I also have a few images of product that were taken with digital camera, I need 3 images of the product cleaned up and made to look professional and nice for sale on website. Should be a very easy project. Must be able to complete within 24hrs. Thanks.
