1) Don't try to undercut Starbucks. You're better, right? Fresher, hand-roasted, local, tastier? Go check Peets and SB's prices at the supermarket and SB's, and shoot for that. It shouldn't be hard to justify to people. Use a slightly better bean if you must to help justify, and really prove yourself. You could always introduce a 'budget' or less expensive bean later.
My whole outlook is this: the market is FULL of mediochre > terrible junk. Why should I try to out-underacheive everyone? The high-quality coffee market in LA is finally starting to catch momentum, and I do have competition, but it's not saturated, and I can fill a niche.
In your situation, your market, too, is FULL of crap coffee. Before you came along was there a shortage of Folgers, or Nescafe instnt? Was Starbucks turning people away at the door? No, so how are you going to step into a market full of junk, and compete? By providing more junk? Or providing something better?
Be Porsche, let everyone else make Corollas. In this case, almost EVERYONE can afford the porsche of coffees. The very best from Colombia can be had for $5-6/lb green, and sold for $18/lb. Not everyone will buy it, but I always ask: how much was your latte at Starbucks this morning? $4? For one drink? And you can't afford 25 cups of my killer joe for $18?
Yeah right.
2) Your wholesale pricing structure is kind of weird. $1 off per lb? If you raise prices to $12-$13/lb, then give 25-30% wholesale discount, it makes more sense, I think.
3) Don't forget shrinkage: 100lbs green is 85lbs roasted, approximately, depending on roast level/style.
4) YOU TOUCHED MY ROASTER? I HATE YOU!

lol, damn, I can't wait!
5) Post pics of yours! What color did you get? What options?
6) You need to get the local social cafe buying your beans. MUST. Win them over, get bags of beans for sale on the counter. That's your main competition, take em out at the knees (by roping them into your master plan of complete domination!).

Offer free training, teach them to showcase your beans in the best light possible.
