I'm usually not this eccentric, but given your requested "fervor," I will write this very bid in an emotionally powerful way :)
(Obviously, I don't know your company, so much of this is made up).
"We had the vision, and we believed in it - that was 90 percent of the equation to our success. The remaining 10 percent, where most others fall off, was the toil. Especially today, others would prefer to try to get around the hard work. Those are the one-hit wonders; they blaze brightly and then burn out just as quickly. No, for real staying power, you must go through adversity. You must not shy away from challenge. That's how we made it here, and that's why we're staying."
You get the point.
Now on to the cliched and robotic self-promotion:
I'm a freelance content marketer of 10 years experience. I have written more than 550 blog posts, articles, press releases, and other forms of web copy for clients across the globe, spanning every conceivable niche and sub-niche. I'm a native English speaker who NEVER uses software (beware on this platform) to deliver work.
If selected for this assignment, I will not waste your time. I won't haggle for a higher rate. I will simply determine your exact specifications and deliver a quality product.
Thank you, and best of luck.
