This is a good time for some business planning. Don't shudder--I don't mean the full-blown formal document, but rather the core and essence, the essential business strategy, the key action points, and--yes--reasonable estimates of sales, costs, expenses, and cash flow as you grow.
Strategy is focus. Are you focusing on what you do best? On what some identifiable people want really badly? Research your finance question and do a good search of www.sba.gov,. If that doesn't clear it up, contact your local bank and your nearest small business development center.
