I'm looking for someone with NLP knowledge. What was your specialization? I'd be interested in having a one hour consultation to get some brainstorming ideas.
Also, are you familiar with which technologies in relation to the NLP?
If not, can you really understand they work and how you fit in? Consulting is less than half technical, it's more business and sales then technical details and solutions. Your proposal has to work with their current ways.
One way is to get into industry, make contacts, build a network, become someone they come to with questions on this stuff. Then you can go independent.
Another way is to go do some time at a large consultancy.
