[Question] What do you do about Overflow / Subcontracting?

When I began working in my VA business in 2005, I got so busy that I needed to hire subcontractors to do some of the work, specifically transcription services. I was just wondering whether anyone has had a time when they felt a need to subcontract their services or get an assistant.

More specifically, as a Paralegal VA, when dealing with attorneys, do you feel it may be unethical to do this or do you have a clause in your contract that states that some work may be subcontracted?

If you've subcontracted work as a Paralegal VA, how did it work for you? What type of work did you subcontract and did you subcontract with someone you were able to physically meet to discuss or did you do everything virtually?

I'm trying to get my ducks in a row. I hope to be VERY busy in the next 90 days!!
