If you have been doing something for 14 years, you should have learned quite a bit about what it is you are doing. The consulting skills are mearly skills to enable you to tranfer that knowledge to whoever needs the skills.
step one: promote yourself as knowledgable in the field of your choice.
step two: read up on consulting ("the intelligent client" is a publication from one of the professional bodies and provides good material)
step three: join a professional body such as the institute of management consultants to rub shoulders with other professionals and network, network and network.
you are selling yourself!!!
PS: if all else fails, try to find a job with one of the big consulting firms, but be warned, if you have been your own boss for some time, you might not fit into their straight jackets easily.
