Graphic Design - Help Re-size, Clean Up Some Vehicle Icons

Hi there. I have a bunch of sets of vehicle icons I got off the internet. I just want someone to re-size (if needed) to get a complete set ready for me of icons that are all the same size, so I can just drop them into my website project. You may have to re-draw some or remove watermarks that are partially covering some. I'll show you which ones I like from each set. I'm hoping to have about 10.
