Hi,
Your question is super long, not 100% clear, and your attitude is negative. Not the best approach if you need assistance from people.
In any event, I help train people to give investor pitches and to be public speakers/lectures. I also teach entrepreneurship at a university and give guest talks.
I'm happy to give you a free 15 minute call to try understand your needs and your products/services. After the initial call, if I have any valuable advice, we can schedule another short paid call.
I've successfully helped over 300 entrepreneurs and would be happy to try and help you.
Be positive, positive things will come to you.
Good luck
