What I am going to say will be brutally honest, so, put on your bullet proof vest. How can you be a consultant in a field that you have no background in and you just learned it? To be a consultant, you should have at least 10 years experience in the field, at a minimum. The first thing that people will ask you is how much experience you have had, and if you say none, I’m sorry, but, what are you going to tell someone who has been in the field all their life?
The best thing to do is to try to find a job in your field and learn the trade and build up your knowledge base. Use this experience, the good and the bad, to build up your resume. Get some certifications in Project Management and other IT specialties.
I have been in the IT field since the 90′s and this is my second career after the military, 21 years, and I am not even considering the consulting field until 10+ years in the civilian sector. There is still a lot to learn.
I hope I have passed on some sound words as they were not meant to insult, just honest, free advice. Good luck in your career.
