PHP, Redis, MySQL, JSON project

I need someone who is experienced with Redis and PHP. I need a performance based application which can take XML, parse it, and store it within the most efficient Redis store possible. The idea is that we can PUSH the updated data via JSON to the JS front end to each client. I am more than happy for alternative suggestions on this methodology, however the important key is this: We have a large number of users, they will all be reading the same information, the data must be read via Redis so that its lightning quick and you dont suffer any table locks like you do with MySQL.
