Build an app and a web software for a new ecommerce model

I'm basically looking for a software developer, as a co-founder/owner for this project, and for other software projects I have. I can't really afford to pay much right now, which is why I am offering a 50% equity stake in any project we do together. Please contact me ONLY IF YOU'RE NOT BUSY WITH SOME OTHER PROJECTS, because I don't want to waste your time, and I don't want to waste mine as well. Kindly refer me to previous developments you've done before, (web dev & apps), then I will spill out the first one I have in mind... Look forward to partnership with you...
