Ask HN: Which startups will let me sell for them on a commission basis?

Recent college graduate, currently a marketing intern, but I want to try out sales before I decide which job to apply for by mid-summer. I don't have much sales experience but I want to learn by doing. Which startup (preferably in the Bay Area that has reached some level of traction) will let me sell their product on a commission basis, remotely in my apartment, working part-time? My end goal is to improve my sales skills and get a job in Silicon Valley by July. Thank you!
