Yes, that you should be better able to justify why you are the right person for the job; after all, it is you who is asking for money and questioning the competence of others. In any case, you are not able to convince me, and on the basis of the other comments one can assume that this also applies to others. It's not enough that you are very convinced of your own abilities.
My CV and other writings and most especially my work itself pretty extensively justify that I'm the right person for the job. Of course, it's probably pretty hard to tell without significant Common Lisp expertise...

You don't need to be a race car driver to debunk a sales man trying to tell you "This is the best car in the world!".
My advice to you is to be humble, you're clearly passionate about Lisp and turn that into a positive thing. Saying Lisp is the best language in the world is a sweeping statement, something a snake oil salesman would put across.
I first used Lisp more than thirty years ago (back then on the VAX), but I still don't understand why it is supposed to be the "best programming language" (as some people continue to claim). It is not even obvious to me how to recognize a programming language as the "best" one. The advantage of the simple syntax is paid with several disadvantages. Praising Lisp for its simple syntax is like praising a protein for its simple structure consisting only of a chain of amino acids.
Fairly extensive advocacy pieces already exist, and we need even more sophisticated ones, and better infrastructure overall, and it would be much easier to do that with proper funding.
It does not help to "prove" an assertion by making further unsubstantiated assertions.
Why is Lisp the "best programming language"? How can we recognize a programming language as the "best" one at all? Why do "we need even more sophisticated" extensive advocacy pieces? What "better infrastructure" is required for what purpose?
