Try going to your local library and see what they have there. John Brookes was a very good designer but maybe a bit old fashioned now. The Marshalls catalogue is a good place to start - lots of pictures and some good design tips. Cleve West is a designer I like - perhaps have a look at his website.
Start with measuring your garden accurately and get that down on paper. Make it as big as you can. Use lining paper or buy at least some a3 paper. Note which way it faces, any drains, stuff you need screening etc etc. The JB book will guide you through all this. You then need to make a list of what you want in the garden and what you need in the garden ie clothes poles, shed etc. Once you have decided what is going where on your plan, you can go out into the garden and mark it out so you have an idea of scale on the ground. .
Before you get your landscapers in, you must have a good idea on what you want, where you want it and how big it is going to be. They may or may not have some ideas of their own.
