As I can see, you have received many proposals already. I am sure the people who sent them are capable of doing a great job.
However, I would like to say a few things that make working with me a great experience.
I like to make the client as satisfied as possible: so I am very good at taking criticism and suggestions until the job fits the client's expectations. I am very good at managing my time, so the task would be done by the time it is expected to. I enjoy simple results that are easy to use and I am sure Excel is a great tool to get them.
Let's hope we are a great fit, so we can both be happy with the results.
