It's actually getting very difficult to find a free home for lists of that size (2500 subscribers). With just 20 postings a day you have 50,000 messages to deliver, and this costs non-negligible amounts of money. It can mean the difference between having to upgrade your hardware and being happy with it until the next fiscal year, so it's probably going to take more than a single smile :-) AOL and eWorld both host large lists for free and this is where I would apply.
