The size of your company really dictates 'typical' sales growth.
10% growth for a $10M company would be an increase of $1M - and would require three or four new crews, trucks and likely some level of sales/management to get there.
10% growth for a $300K company is just a few new jobs - and could likely be done without the need for any more hires, equipment, or overhead expenses.
There is no one-size-fits-all goal for companies. Start with a reasonable, realistic goal, then fill in the rest of your budget. Your profit and loss summary will help you decide whether you need to grow more aggressively or not.
