Get my e-commerce websites generate some return

I went mad and bought few e-commerce websites. They are supposed to generate income (at least pay me to maintain them). These site are good and works. I am trying to advertise my work using these sites. The traffic is good but I do not know how to manage them. Need e-commerse or expert in word press to look and organise them. If I like the work you do, then may hire you to help organise my work on long term 6-12 months
