No one gives a damn about "I, I, I, me, me, me..."
"I did xyz... and I want xyz... and for me, I want... and I do... and I'm..."
People want, "...for you, can be done... value to you... profit to you... minimal risk to you... incentive-based, so you only pay me as work is delivered..."
People are persuaded by appealing to their own interests. If you give an I/me centric story to persuade a savvy business person to do something, you're instantly getting written off 90%+ of the time. If you can show someone that you can do amazing things for them, they'll choose you and you profit.
"I have many skills, high standards, and can assume any roles necessary to help you succeed."
Odd that you would assume that anyone in HR is incapable of starting their own company.
An impressive feat by an impressive individual, it seems. Wish you all the best!
