Hellou.
Im php/mysql/html programmer with over 10yrs of experience, specialised with osCommerce stores.
During hat time i was also developing own modules and evolving existing ones.
I have no problem in using english , and my last jobs here can help you see that, as most of therm needed direct contact not only with employers, but also server support, ERP documentation and so on. We can freely speak not only through e-mail, but also live - like on chat.
What i would like to know, is if you plan using any additional libraries, except the ones you already have. I mean jQuery , mootools or any other. Page has to reload, or it may be done in ajax call, which will update top cart info ?
ASAP factor means that you need this done by the end of the day - lets say next 17hrs ?
Best regards,
