Would you find use for a "Gig Barter System" for Sellers who want to Exchange/Trade services with each other?
It may help the overall Buyer Experience here if Sellers were able to trade one Expertise for another.
Perhaps SEOClerks can make it a requirement that the Seller "Seeking" to trade Services with another must offer in exchange, a service that is of "Higher Value" to whichever Seller they approach.
The "difference" would simply go to SEOClerks as their Commission.
For example, if you have a service that is $5 and I want to trade you for one of mine, I would have to offer you one of MY services that is at least $6.
SEOClerks gets $1 (which is taken from the "Seeking Seller's" Balance), we Trade Services and can also leave each other Feedback!!
