How many letters does your 1 employee DM dept. push out per hour?

[Benjamin Cowles]

I just hired a lady that I'm concerned about her ability to just learn new things regardless of her current lacking computer skills so I'm thinking of either paying less to train or by the piece mailed. I've been able to teach her but it takes a while and some psychological skills. Even considering 'coaching pay' below training. But I figure if I can get her on just one thing at a time I could get some worthy performance. She's been through tough times and currently living off someone's couch so I'm thinking a pay-per-job scenario might be best initially. And she's very nice which is pretty important for me. So for min wage how many letters/postcards should I expect to get an hr?
