Retail shop front design. - repost

We have a small shop front in a shopping centre that needs to be refreshed and made to be more modern. The Business is an English learning centre for children. We need to make use of the existing brand logo and colours, however need to add a few elements to the window to make it more professional and finally need a rendered image of the finished product and a dimensional drawing for submission / approval. The shop front is entirely glass, however it will require new printed decals for it and the addition of thin wooden display cabinets behind the glass. These will be manufactured using the dimensions supplied from the drawings. You are only required to design the shop front decals, trim, and display cabinets.
