If you are doing 6 figure monthly revenues, one thing worth considering might be to read some mr money mustache and really contemplate what you want for your life ... You aren't required to grow 10 or 100x ... You also have the option of pocketing profits, living frugally, and retiring young. That's one of the big advantages of bootstrapping.
6 figure revenue means nothing without knowing margin.
Disclaimers: 1. I work for Vistaprint, so possibly a competitor though we shuttered our photo printing business years ago as not profitable and without a clear path to profit. 2. Your site is constantly crashing Safari on an iPad original. (not complaining, just explaining why I don't know what you actually do) 3. All content and opinion in this post is mine. I don't speak for my employer.
