This will be an ongoing project for developing a Magento website. You will need to implement the uMarketplace extension and then customize it. You will also need to install a theme (that I will purchase). I would expect this initial project to take under a month, but if all goes well I will need someone to work on the site regularly. This would include routine maintenance, but also some customization.

To add, I am expecting this to be around 10-40 hours/week, and taking no longer than a few weeks.
