In my experience, the ipboard script needs to be customized for each site (at least every time I’ve used it–maybe 5 times?). Given that, it’ll be hard to do the job in 4 days. I’d likely charge a minimum of $1000 if only very minor tweaks to the script are required, so if anyone else thinks they can meet this budget, don’t hesitate make an offer.
