SwapThing.com, an online swapping site, has launched SwapServices for service providers to advertise their business and swap services. According to the company's press release, "Swapping with other service providers or users is a great way to obtain items and services for a business or for personal use, without spending any cash and it is also a great way to advertise. SwapServices is completely flexible, and individual service providers and potential customers can negotiate the terms of the swap privately." The SwapServices functionality is subscription-based and allows service providers to fully advertise the service, locally and nationally. SwapThing.com integrated with the portable feedback service RapLeaf last month.
