I have a business acquaintance that is running a huge shared postcard campaign is looking to get a carpet cleaner on it. these things are pretty cool - i have done them myself in my area. Told her I would put some feelers out.
Sorry for the delay - she is doing a large EDDM postcard with a few businesses on it - the prices are good as it's a shared mailer. i have done them as well with decent results - I can hook you up with her and you can chat if you want.
