A6 sized trade advert creation

I need to create a series of about 8 small adverts (paper size is A6) that will go into trade journal Attached are some examples of previous designs I have done and want to try a maintain the same look and feel However the main look I am wanting to mimic is that of our website [login to view URL] Our business is broken down into the following categories: and I want to use each category as the theme for that advert i.e. Dealership Supplies (heading) and we select 6 products to focus on in that advert e.g. Booster Pac, Autotags, Key safes, Number Plate Attachment Frames, Windscreen Markers, Stock Stickers and T-Card System Dealership Supplies Signs/Displays Flags/Bunting Sales Aids Custom Branded Products Windscreen Advertising Service Dept. Car Cleaning The look and feel of all the adverts need to be the same )similar to the pic above that comes from our website and then all the individual adverts will follow the theme of what we are promoting e.g. Dealership Supplies Signs/Displays Flags/Bunting Sales Aids Custom Branded Products Windscreen Advertising Service Dept. Car Cleaning If that makes sense Can you give me an indication of what you would charge to create 1 main theme advert and 6-7 subsidiary adverts Deadline for at least 2 adverts will be Friday 29th July 2016 Many thanks
