PHP Programmer with WHMCS Integration Knowledge

I need someone who is proficient in php who can start writing code immediately. The project will be for 4 days approximately. But this may continue for more time if we like the coder. I will let you know the exact requirements of the project once you send me few samples of your code (~100 lines) - I want to see your coding style, error handling etc. Please bid with the projects you have done. If you have done integration for WHMCS (really it is simple php) - please mention it as well. We are looking to get started ASAP. Also, you will need to work US timings.
