Outsourced HR Help

Hi there - I'm the CFO of a small 30-ish employee design company. We previously had an HR director who left for a larger role. In hindsight it seems clear that they were underutilized as a full-time HR person for us, but now we have gaps and I'm looking for ways to fill.

I am currently processing payroll every other week (we use Paylocity), which I can continue to do. What we specifically need is someone to:

• Manage 2-3 departures and/or hirings per year for a variety of roles
• Compliance related tasks
• Be the 'HR presence' when needed (does not have to be on-site)
• Oversee other people-related items that I'm not thinking of

To me this seems like a part time role, and could easily be done remotely, but I'd really like to have someone well-qualified. Does anyone here leverage an outside resource, either an individual or a big company (Bamboo?) for things like this? Recommendations on how to proceed, who to look for, what to avoid? Thanks!
