Correctly set up port forwarding on my router to allow me to access my 'Foscam' webcam remotely

I have purchased and set up a Foscam FI9821W webcam ([login to view URL]). It is working correctly within my home network, however I have had no success in setting up port forwarding in order to access it from outside my home network (dynamic IP). I am looking for someone who knows what they're doing, to remotely access my macbook in order to set up port forwarding for me. My budget for this is $10, as it should be a fairly straight forward job. Payment will be made once the webcam can be accessed from outside my home network. Thanks!
