The HBR Guide series has some great titles. The nice part is they're often written by multiple experts so you can focus on chapters that are most relevant to you.

Performance Management and Thinking Strategically are two foundational titles with some great chapters applicable for small business.

As for building a sales team from scratch, I haven't got any specific titles. There are lots of considerations: sales strategy, lead sources, hunter/farmer mix, compensation model, performance management, your own strengths/weaknesses etc.

In my experience a common mistake is adding bodies to add sales when there are diminishing returns without the right funnel and segmentation strategy.

Execution by Larry Bossidy is a classic.

Traction by Gino Wickman

I think you’ll do better if you figure out the specific problem(s) you’re looking for an answer to and then talk to people whose experience you can tap into. Most books are pretty dogmatic (‘this is the one and true way’) and may not be relevant for your company.
