Use http://www.yeptext.com for text message marketing and/or notification. This is an opt-in service, with opt-out instructions in each message, so this is not a spam delivery service.
Send me a PM, and I can send you a promo code for 30% off the first month of service.
The service can be used for the hobby (I will provide my thoughts on discretion) and for non-hobby businesses (I can provide ideas if you're not sure how to use it).
I can help with setup for a fee (negotiable), but you'll have to come to my town (non-negotiable).
Due to my excessive paranoia, I will not reply to "newbies."
