Growing Pains

I came from a large staffing and recruiting org (12 bill annually gross revenue) to a niche specialty contractor that does around (1 bill annually gross revenue) to grow their national service division. I've been able to take it from 188k (in 18 months prior to me) in revenue when I got their to 3.5 million in revenue in 18 months. Due to how much business for either service or inspections I requested help, since we are missing opps to bid on. I was thinking of a second sales person that I would train and develop and made those ideas known. What I got instead was a sales assistant intern still in college. Individual is sharp and I think can learn at a high level but not sure if this option will is an accurate response to the growing needs of the division. How should I navigate this situation, I believe this year alone we could double our revenue with a 2nd full time sales individual? Sales cycles can be anywhere from 1 month to 12 months depending on various factors. Input/advice would be great! Thanks war room!
