I have a web service that includes sending some information trough SMS text messages. The service is completely free for the end user. Every message sent has about 50 unused characters that could be used for advertising (e.g. Sponsored by: ...) to cover the costs (and bring in some money). Does anyone know of existing service that would help me find such advertisers? Or do I have to start from nothing and find them myself? Regards, z
Adsense (on webpage) can only cover small fraction of the costs for txt messages (international rates for bulk SMS delivery is $0.05/SMS) and the main part of our service are those txt messages (and not the web page itself). So I guess "standard" advertising methods usually used on web pages doesn't work here.
