Codeigniter Library: Google Adwords API

I am the head PHP developer for a search engine marketing company. We are working on a PHP project and are looking to outsource some sections of the code. SYSTEM SETUP: PHP 5.3 Mysql/5.1.37 Apache/2.2.12 Ubuntu PHP FRAMEWORK IN USE: CodeIgnitor [login to view URL] PROJECT DESCRIPTION: We need the Google Adwords API examples located at [login to view URL] to be converted into a single Code Ignitor Library/Class that we can use in our own application. Each file located in ...\aw_api_php_lib_2.3.0\examples\v201008\ will need to be converted into a function of the this class. All the functions will pass any needed variables/arrays when called and will return an array of the results. The idea is that we can call the library in our CodeIgniter controllers, make a request using the library, and get an array of results to process. GUIDELINES: This must be coded as a CodeIgnitor Custom Library. Do not use any functions that are deprecated as of PHP 5.3. The library will be one file with one class along with the functions being named like the file names in ...\aw_api_php_lib_2.3.0\examples\v201008\. The library will call any necessary files from \src\Google\Api\Ads... EXAMPLE DIRECTORY STRUCTURE: \application\libraries\api\[login to view URL] (custom library class) \application\libraries\api\src\Google\Api\Ads\... (google's code)
