When talking about creating your presence product . have two options; free marketing and paid online marketing. I use a combination of both to promote my wash and fold service. Free marketing would include listing yourself on free directories such as Google Places and Search engine! Local. Craigslist is another great source to promote your nearest coin laundry to me as a gift. Paid marketing are the sponsored ads find on bing and yahoo results pages; the top dogs are Google Adwords, Yahoo! Search, Microsoft Advertising and Facebook Ads. You will find more free and paid online marketers but this is an excellent starting problem.
If you'll want to to do laundry delivery service, obtain fax, find a delivery (FedEx, UPS or DHL type), get a shower, just plain get off the road for several hours- a truck stop is a safe bet. A truck stop guide will inform you what services the truck stops have and provide the phone number if anything to call ahead to obtain the fax number or address.
