Convert the freelance consulting to a consulting agency. The business model is now to hire one more person (either a colleague or someone new) and have them help out in the work. Once they are billable start introducing your clients to them and canvass them for new work. Build this upwards like a pyramid - You on top with highest billable rate, associates at a lower rate, and below them junior associates with minimal rates. Over time, if the people are good, you should be able to get revenue from their work.
