What you describe as your interests suggests that you are (and don't get me wrong when I say this) going with the flow and what's of current vogue; the intellect claiming to use Body Language, NLP, Suggestions, etc.
In the 80's two type of acts were very popular, the Channing Pollock styled Bird & Manip act and the Grand Illusion "I want to be Copperfield" act. Both viewed by insiders as "Clone Acts"... they were all the same, same general content, presentation style, etc.
I bring this out ONLY to challenge you a bit when it comes to originality and allowing yourself to be a bit more than the same old thing everyone else claims to be these days a.k.a. a Derren Brown or Banachek clone... and trust me, even when you think you've changed things enough to escape that association, talent buyers and other trained eyes will see it. So try to be more creative with your effort.
That said, within the vein of what you describe you could include a bit of magic. Kreskin goes so far as to say that one of his hobbies is Magic and "here's a neat thing I just picked up..." it works for him and it can work for others so long as they segregate the two genres.
In the early 20th Century most of the better known performers, including the likes of Annemann and later, Dunninger, did an early evening Magic Show for the whole family but later in the evening presented a program for the more mature and intellectual or curious audience in which they explored the potential of the human mind, the power of suggestion or matters of the occult, etc. They deliberately created a stronger level of intrigue when it came to these presentations, evoking a sense of believability in what they were offering... at minimum, the possibility associated with such things. This is very important when you are attempting to do solid mentalism vs. mental magic. The latter is far more commercial as well as entertaining; even the big names inject a fairly large amount of Mental Magic into their shows for the sake of levity and production value. At the same time they carefully weave the fabric of enchantment when it comes to how and what they claim, present and cause to appear to be viable. The more real, tangible and even logical you can make your presentations the greater the public investment of belief and thus, the easier it is to do your job.
My suggestion at this point, is to look around and weigh your options. I'm confident that you can find a civic theater group willing to accept another amateur into their ranks. There are all kinds of improv groups that are 100% FREE via which you can gain a tremendous amount of experience and that's what's important... even if you're working back stage (which is where I spent the greater portion of my career... as a technician and illusion mechanic).
The other thing I'd do if in your shoes, is study the industry trends as well as the available market. You also need to get very real when it comes to what is genuinely available to you should you embrace the image & theme you've described vs. the more mystical "Psychic Entertainer" mode of Mentalism which gains the advantage of home parties, working psychic fairs and a wider sense of venue in a way that's a bit more
flexible than the other.
I'm not putting down that other style, the Dunninger Mold approach is well established. Unlike the aforementioned however, this mode of course requires you to depend on the more traditional "Show Biz" way of doing things; agents, talent buyers, and investing all of your "spare time" into hustling and selling yourself and your act into the same markets all the other enthusiast are doing.
Once again, you need to think about this... if your penchant is the same as all these others; leaning on Ekman, Ericsonian Techniques, NLP, etc. WHAT MAKES YOU STAND OUT? WHY SHOULD ANYONE HIRE YOU OVER THE DOZEN OR SO OTHER ACTS CLAIMING THE SAME SKILLS?
There are subtle things you can do when it comes to "packaging" yourself and creating a "Brand" but you must first invent the product, defining it in a way that makes it "more" than the rest.
