Design a flyer/poster

I need one of you brilliant designers to help me launch my business. It is simply a toddlers class called Froggies and I need to produce a poster, A board and flyer asap. The class is mainly movement, sensory skills and educational. I do have a website so, if some of the work can be transferred on to that, that may be helpful. Happy if the poster and flyer are pretty much the same design but, different sizes.
