I like your proposal, and I would be willing to work with you to grow your business. That means I can start at a low rate and improve it as we succeed together.
I am an American who speaks U.S. English perfectly, and I have a lot of experience in public speaking. I love sports but am not an expert in any of them. However, since you are providing the scripts, and all I need to do is read them, that shouldn't be much of a problem.
I do want you to know that I am an "older gentleman" so if you are looking for someone young and sexy-looking, that wouldn't be me. On the other hand, news readers tend to have more credibility and respect, the older they get.
