cURL, php - imitating a browser

I am looking for an experienced php programmer. To be more detailed - a cURL expert. I need a class 'wrapper' which would allow usage of cookies (logging in to a site), parsing a little bit of data and filling a form ( _POST request ). No 3d party codes! (I mean c'mon, I need a specific stuff, you can't find it on google, if It would be possible, I would do it myself =D ) No mumbo-jumbo linear programming, needs to be in OOP, I also give a shit about clean code. You definately need to know what memory_get_peak_usage(true) is! More info upon request. No slavetraders (people who re-hire other people for few pennies to get the project done) or other type of pimps!
