A start up recruitment firm has sizable number of clients and a decent recruitment team in place. It has managed the show well so far but wants to scale up the business to next level now. But being a start up it has limited resources. 

Now as a strategic move the company wants to decide between either going after new clients or hiring more recruiters to ensure that it does not miss out on commitments and delivery excellence.

One worry is if it hires more recruiters in the anticipation of new clients coming in and if the sales efforts do not fructify then it looses both on the cost front also there is a risk loosing recruiters who get disengaged with the drop in activity. 

How does a recruitment firm ensure that it balances the growth and delivery aspects. Suggestions and ideas are welcome.
