Sounds like an interesting product, presuming that you have managed to identify your unique place in the market and that your infrastructure can handle a large influx of business you could try partnering with one of 2 types of business.
1) Grocery stores - preferably national and online (If such things are as common in the USA as they are in the UK) - Offering discount vouchers upon sign up. Assuming your charges to consumers is $72 per year ($6 p/mo) - $100-$200+ worth of grocery vouchers would seem a good sign up value. In addition it won`t increase your costs as you will get these free from the grocery chain.
2) My company`s area of expertise is primarily Direct Response Television (DRTV) or commonly referred to as paid programming/Infomercials. If you can find a partner who is selling on a national scale and their product is complementary. Think Foreman Grill, Jack La Lanne Power Juicer, etc then they take literally 1000`s of calls per day and spend millions in advertising. You can negotiate a deal where they read a short script selling your product to everyone that calls. You then pay them a % of sales.
Do you bill monthly at $6 or an annual fee in advance? If only Monthly. maybe a reduction for an upfront annual payment - you can then split this will the infomercial company.
Would be happy to go in to more details directly if you need it. Snowflakemedia@aol.com
