Design a Website Mockup

I have recently moved to Newcastle in Australia. I am looking at setting up a colour and design consultancy and small project management business. I will need a website that gets the customer interested in using my services from maybe a basic colour consultancy to build design and complete interior exterior renovation. I have completed four medium size projects in the last couple of years that have photographed well. I have designed a glass mosaic plunge pool for a space in a backyard that works fantastically well. I work on the design from the start to finish with my structural engineer. Basically I need a site that can offer my clients solutions to any colour or design ideas that they may have themselves.
