Let me say this. You get what you pay for. Just don't irritate possible customers on this site by posting multiple spams trying to flog your products. I can't believe anyone could possibly imagine you could sell something by pissing people off.
Start small. Advertise locally. If your business grows, then it's time to expand. Most people go into business with big ideas and set impossibly high goals. Set small, realistic goals. Go step by step. When you reach one goal, set another one higher.
