Create a new logo for a multi academy trust

Information for the business: We are a group of schools who have formed a multi academy trust
Industry: Education
Brand name/slogan in logo: learning in harmony trust
Ideas for the visual style: We need a design that can be amended easily when new schools join the trust
Where the design will be used: web print and merchandise
Extra notes: We are a group of two schools Sheringham (http://sheringhamprimaryschool.com) and JFK (http://www.johnfkennedy.newham.sch.uk) who have joined together to form the learning in harmony trust (learninginharmonytrust,com). We will be joined in September by Upton Cross Primary School (http://www.uptoncross.newham.sch.uk).

We need a combined logo that includes the logos of the three school but has the phrase learning in harmony trust in the font and style already designed at its heart. The logo also needs to be designed in such a way that the logo of upto three further schools can be integrated.
