Make sure you create some marketing collateral  a professionally produced one page brochure covering your services, credentials, fees and contact information is a must for starters. Next start social networking. Join LinkedIn, set up a business Facebook page and start Tweeting! Schedule time for social networking tasks so it doesn’t take over your life but it will help you expand awareness of you and your business.
