would you be willing to share some plans of what exactly an employee would do for you?
Yes of course... There are two key functions...
Developing the pool website/app such that it's comparable at least to other multi-pools. i.e. Charts, reporting, user stats, mining functionality, etc. This is both front-end web development and backend code.
And, managing the operation of the pool - Adding new POW coins, fixing POW coin daemon issues, monitoring logs, initiating exchange transfers and payouts. As the pool scales and payouts reach 1,000's BitUSD per day this becomes more and more important.
If a single person can do both then great, but it's not necessary...
