One-Person MSP Business Acqusition

I am looking at MSP space and want to hear your thoughts on a One-Person MSP. deals. The one I am looking at is a small Cloud solutions provider for Legal and Medical businesses to meet regulatory and compliance requirements. On one hand I understand the risks associated with it in terms of technical knowledge, customer relationship, growth potential, etc., on other hand I believe I can quickly get up to speed on technical skills and then hire/train a resource to handle the technical work so I can focus on marketing and acquiring more customers. Please share your thoughts/experience.
