Question
I'd like something that keeps images of business cards, maybe something that has some bulk e-mailing features, and tracks basic stats like conversion rate and such...

There are so many CRM options depending on your immediate needs and long-term goals. I have used ZohoCRM, karmaCRM, worketc., and bit of Salesforce; each has its own merit
