Resize 500 eps images to png 5 sizes 300 dpi

I am looking for long term freelancer for my magazine. I want the relationship to be long-term because we will be doing work every week of the year. So I want somebody who's consistent responsible and has perfect consistent touch. For first job I have 500 standard illustrator images that need to be re sized in 5 different sizes at 300dpi to use them as background. Please bid accordingly. The images need to have elements fixed for its size, shape fixed proportional. The end result is perfect professional look!! Need to be magazine quality when finished 300 dpi. Need to have perfect final shape and look according to size. Size in inches 300 dpi: 8.625 X 11.15 8.375 X 10.875 3.625 X 9.75 7.375 X 4.75 3.625 X 4.75 Images should be png extension. I attached 1 image and the 5 sizes samples how it should look, ready for magazine. All text from images must be removed and any other layer that will make it no usable for background. You can see that I change the center shape size accordingly so it can maintain size relation with whole image. I want to see if you are creative and good with shape theory to improve the image to different sizes magazine quality. Please take another business card and make a sample of your work to proof your skill on design. All images are different, this is a particular case of business cards. Work should be deliver in a daily basis to check images have the requirements needed. Payment should be once all images are done perfect. Thanks.
