Business Identity Package

I need a business identify kit for my new non-profit 501(c)3 company--logo, business card and stationary design. We are an educational/training company that will teach children and adults practical life skills. We will be soliciting grant fuding from large private foundations to provide money for our training and educational programs, So, our look has to be professional and very high quality. Let me know if you have experience with business identity in the training, education and motivation industry. Please provide examples of your work so I can see your style. I would also like to know your standard procedures with regard to the number of inital designs and the number of revisions you allow until we get what we like. Thank you.
