I was hopelessly looking for assistance with my dissertation after having a bad experience with another company (they were unreliable and unprofessional) I interviewed a number of businesses where both an editor and statistician were offered and found Statistical Agency. 
The statistician and editor I worked with were both amazing. They were experts in their craft as well as supportive throughout the process. They were both fast to respond to questions and upfront about costs. I very much wish I found them sooner as they are great with deadlines and checking in with me about my own deadlines. Lastly, I will be defending my dissertation research with the help of my statistician who will ensure I am prepared to explain all my data. This is a one-stop shop. 
I highly recommend Statistical Agency, Studio Leonardo for anyone working on his or her dissertation.
