Symfony / PHP - Forms Wizards

We're looking someone very familiar with symfony, and symfony forms. We're building a website (symfony, mysql) which is very wizard driven - and need someone to split up the model forms across multiple steps. We also need the forms to be fairly customized "if Yes to radioA, then display field X", layout, etc - the site is to be as simple as possible for the users. There are 3-5 models, each with 20-40 columns needing split across a multi-step process - interacting with each other (some selections will disallow or allow other fields). There is a lot of additional work on this project, and others - so please include other languages, experience. Other portions of this project are already finished, and you'll work with an existing team of developers. ## Deliverables Any schema changes should be present in the yaml files, for rebuilding if needed. Developer should be comfortable working either in their own development environment, or in a linux ssh environment (provided.. screen, vim, mysql, svn, etc). Please specify preference. Code will be checked into, and updated from subversion - with other developers on other portions of the project. Please be familiar with this process.
