For SFA, you say you have CPAs on staff to handle the high-end work and year-round accounting. Are you looking for seasonal help now? Then, an EA or other non-CPA sounds like what you are really looking for. According to you, a CPA would expect year-round work -- and this one might want to grow his business and leave you. Even if not at your expense, not taking any clients with him, as has been said, clients might leave anyway when he does. And, you really can't expect to keep him forever if he's trying to build his own business, so you're back to hiring and training again.
