Targeting small teams seems to be a good idea. I can concur that there are many teams for whom setting anything on servers can be an excruciating experience. But, in my opinion, your offering is too broad. When should a team call you? Should they rely completely on you to set their servers? Should they contact you when something gets broke? What happens when you are not around? What happens if you (in extremely unlikely scenario) 'rm -rf' some important stuff?

But best of luck with your venture!

That makes sense, I commented on similar earlier. Are you also getting the use case of an outsourced "on call" or companies in the "just launched a month ago" category? I would think these would also be good fits in addition to the smaller but established companies like you mentioned design shops etc.

How have you been generating leads? Word of mouth?

Congrats on your launch by the way. I wish you success.
