I need an A5 advertisement for a Green business to go in a trade magazine

Information for the business: Green startup that sells a solar heating/insulation system. More details at skyrad.co.uk
Industry: Environment
Design details: We've bought a full advertisement slot in a trade magazine, and now need to do an advertisement to fill it! - We've done a draft of the wording and can supply you with logos, photos and a couple of outline design ideas, very happy to see what you can come up with though. Main constraint is time. We need to get this to the publishers by start of business on Monday morning
Target audience: Councils, Housing associations, Landlords
Number of pages needed: 1
Content on the front/back side and body: 1 page ad
Ideas for the visual style: Professional, informative, dependable
Things to avoid: Mustn't look amateur. Not too artsy!
Extra notes: Please get in touch with examples of your work. I can send everything through to you ASAP and explain what we've got. I will call you this afternoon/evening to talk you through everything.

If you are familiar with engineering/trade magazine advertisements you'll know they're often really boring. You'll get serious bonus points if you can not only pull off the nice solid, professional, dependable look, but actually make the thing interesting at the same time!

Look forward to hearing from you
