I have attached a logo idea that we have, so the new logo must based on this idea.
Please give me a few options of the logo and a few ideas with different fonts.
I have attached our previous business card and compliment slips in pdf format.
I will need the designs print ready and suitable files provided, I normally use http://www.sensecreative.co.uk/ for printing.
Please also provide a high resolution logo on its own.
I have two business cards, they will be identical but with different addresses on them

I am looking for someone who can create a professional, creative and well thought out logo for our architectural practice. I welcome any good ideas to the table.
