Build a Website

I am involved in direct marketing and speak to about 30 - 50 people a day. 95% of these people are not my target audience, however, all of these people should know of someone who requires my service. I am looking to set up a referral program in conjunction with the design of my current website. I don't need all the fancy tracking graphs and third party people to look after this. And of course do not want the monthly fees associated with a huge affiliation site. This will be confined to locality. Would like people to register as a referrer on my site. Once a referrer, they can post on facebook or send email or even just phone someone and give them a unique link that I can track back to them. Any new signups that they referred, I would like to reward them, not with a comission but rather with a voucher of some kind. Yes, I've looked at infusionsoft and some other big named companies, but that is way to big for me as I am starting out as a small business. Regards, Ivan
