Dojo charting project

My html developer has taken some infographics created with Dojo charting as far as he can go with it. We now need a little help to finish what we set out to achieve so someone with either experience of dojo charting or someone who can write/understand java/php. Some knowledge of development with wordpress may also be an advantage. It's quiet a small job but it may lead to bigger things with my London based creative agency in the future. I can send a private email with details of the job and I would like a flat rate price to complete the job. A developer in the UK is needed and London base would be preferable although not essential.
