Hello. Your project is interesting, because both of your needs require a better understanding of not only your firm, but your target audience. In other words, if you don't know WHO you're targeting with your content, how can you know HOW to create effective slogans and "about us" content?
With that being said... part of working with a professional copywriter (Yes... me), is the fact that I will create a customized creative brief for you, so that WE understand who it is we're targeting, and WHAT it is we're trying to convey.
If you would like to discuss possibly working together, please feel free to contact me, or simply click the HIRE ME button to get started. Either way... I would love to know more. Good luck!
