Help me decide on this job offer?

I’ve recently graduated college and am working at the same place I’ve worked the past 4 summers. The job is easy, the pay is fairly low ($440 pre-tax) which is ok because I don’t have a great many needs yet, but it’s not a job for a college grad and promises no mobility or even really useful for resume building.

I was just offered a job as a sales rep for a company selling organic foods (all the rage these days). At this company, I’d be receiving a $300 weekly draw, $100 for expenses (gas), 11% commission per sale, plus benefits after 3 months. According to the individual who interviewed me, the average sale is $5,000, so that would be (in theory) $550 commission per sale. There is also the chance of becoming something better, like a sales manager (I have leadership experience, and when the interviewer came across that he seemed excited for leadership possibility), shortly down the line, as this is a new office of an established company and they’re looking to fill it and will be needing people for these higher positions.

I think I covered all that; my question is two-fold. First, for people in sales, does this sound good? I’m in a fairly wealthy area (North Jersey) and the people I’d be selling to would have organized appointments for in home consultation so it’s not like going door to door or cold calling (or so I was told anyway). If I understand the draw correctly, it’s taken out of your commission, right? So I mean if I only make $600 in commission a week, that’s me taking home only $300, which isn’t great. So, advice on that. Second off, should I take the job? It’s not exactly what I’m looking for (English Major, not sure what I want), but it could be fun and in theory make a good amount of money if I’m good (I also did a great deal of theatre, so I’m fairly personable).

What are your thoughts?
