Tools are a great way to start with a project.
A partner scorecard is a great tool to help you objectively compare potential partners, and to identify the common aspects of the best ones. This interactive tool will help you get started.
Using just a little excel knowledge, you can customize the "must-have" feature for your partners, and even weight the different attributes. It also is programmed to compare in graphs and charts how different partners compare.
