Joomla Microworkers site

I m sorry, is this perfect place for this topic?

I am interested to start a Micro Workers like site, but i did`nt get good script for that. I also head that it is possible to do with wordpress or Joomla by using auction plugins, but how? any help from you?

does microworkers sites are good for in asia?
asian is kind of like an untapped country
but they do scams a lot

now Bangladesh is the 3rd largest country for freelancer & microworkers, in this type of site payment through escrow service so no option for scam.
