Are you planning on installing the interior wall paneling on your own? If you do, I hope you have an extra set of hands to help you out with that endeavor.
Your best bet might be to meet with a local contractor who installs wall paneling, as they probably have greater access to a variety of wall paneling products, plus they might have the benefit of a wholesale discount given the amount of installations they do, a discount of which may be passed down to you if you negotiate well with the contractor in having him do the job.
So, call some local wall paneling contractors around for free estimates/consultations. Look at home improvement sites, too.
