I need professional high quality facebook/twitter cover photo's and profile pictures

Industry: Education
Target audience: Parents
Kind of design: Facebook cover
Design details: I own a company called Little Learners which is expanding every day. We are a messy play type pre school class where we learn how to write through play for under 5's.
I need an eye catching, professional, high quality facebook cover photo and profile picture which portrays our branding logo, photo's and our characters. I would like a profile picture too which is HD.
I also would like (if possible) the cover and profile pic slightly changed to each licencees area. e.g Little Learners Newcastle etc.
I really need this to look good and if possible I would like to keep the same designer to do any future work I would need doing in terms of deisgn work for Little Learners.
Ideas for the visual style: Colourful. Our main colour is purple. eyecatching. simple but effective
