I started out on my own 23 years ago; there were good years and not so good ones depending on the economy; I found the key to successfully 'staying alive' is making sure your name is out there. Network with similar businesses as yours as well businesses that may not necessarily do what you do but would have clients you could help. Eventually a referral will come through. Always have a pricing profile that can be provided to a client - give them the product/service that you promised and charge them accordingly.  They will remember you for that.
