Be careful about raising the prices to your best and continued customers. I work for a large engineering/procurement/construction company. We have lost two good long time customers recently. I believe those losses were because we raised our rates. Now we have to bid to these same companies, whereas before it was just gravy in the door. The profits weren't big but, bread and butter on the table is worth something compared to an empty table.
But then maybe the other post are correct in that you may have to move in order to make more, but moving may also cost you more to provide for your family in increased housing and other cost. Consider all your options carefully.
