Betfair API Bot Application PHP or Javascript

We are ideally looking for someone who has experience of the Betfair API. We are looking to develop a betting bot that ties in with the Betfair API. This server based interface, can be written in PHP or Javascript or any code that runs on Unix servers. Betfair offer sample code here : http://docs.developer.betfair.com/docs/display/1smk3cen4v3lu3yomq5qye0ni/Sample+Code The bot will use the Betfair Betting API to perform navigation, odds retrieval and bet placement operations. It will also need to use the Betfair Accounts API to extract account related operations such as the ability to retrieve the users available account balance. It will pull information only from Betfair Exchange See Betfair Developer Area here: See: [login to view URL] The software will need to at least achieve the following basic functions: 1. It will need to be a secure server based interface requiring login and password 2. Each user will be logged into their Betfair account via the software 3. It will pull in all the ALL horse races from the Betfair Exchange using the API 4. User will be able to choose a horse and queue it to be bet on before the off 5. Uses must be able to set stake either a flat stake or a percentage 6. The results would need displaying in the software. Most likely more software functions will need to be added as we progress so this could be a long term contract.
