I am sure I could help you do this. It is hard to say too much without seeing the actual card and having some idea for what kinds of things you want changed, but I am sure whatever it is: I can produce results that you will be more than pleased with.
More to that point, I am new to the Freelancer community (I just joined today, and am still working on uploading and updating my account), and you are actually the first project that I have submitted a bid for. Now that is not to say that I am new to graphic design in any way (as I do have a fair amount of prior experience), but basically I am looking to establish myself here and garner some feedback as to my capabilities. That is in fact why I entered such a low bid: I just want to get started on here and get some work done.
So basically what I am saying is: I will go above and beyond the call of duty if it means I can earn your business and a positive review :).
Thank you for your consideration, and I hope to start working with you on this project soon.
