Hi. I want to put a picture onto a business card. However, the file I have to work with is only 600x336, whereas they require 1062x615. Uploading the file unedited produces a very corroded result. When attempting to resize (and increasing the dpi to the requisite 300), the result is too blurry. The sharpen tool is no use. I realise I may have to fix it manually, but I would prefer not to do that if possible as I am on a limited schedule and I am rather inexperienced. Is there a better way? My source image is here. Thanks very much in advance.
