At first, I was thinking of charging a minimum of $50/month, with a desired goal of $75-$97/month to advertise on my site. Each business is grouped into their respective category and can have unlimited coupons sent to local consumers. I have a great deal with my SMS provider, so I'm not concerned with going into the red with this method. If a business wants to market to their list, then they can pay per message sent in addition. This I've yet to determine due to the concern of the local consumers being bombarded with so many text blasts per week...month, etc. from so many different businesses (IF they're subscribed to multiple businesses).
The benefit I'd provide is a local, targeted advertising medium for local businesses, while offering something isn't even available in my surrounding areas. If someone searches for a business on my directory, they will no doubt see all the other businesses offering coupons (cross-promotion).
Local consumers can now have coupons only they want sent directly to their cell phone, without having to waste time and money on ink and paper, only to forget where they placed their traditional paper coupons.
It can be a "chicken or egg" dilemma, but I've found the caveat to starting something like this is to get as many businesses on the site as possible before promoting it to the general public. To sweeten the deal, offer a full 30 days for FREE.
When going this route, you're shifting your role to that of a creative advertising resource and becoming more than just a mobile marketing consultant. What are your thoughts on creating a Local Mobile Coupon Directory vs. simply creating individual campaigns?
