If you're anywhere near Seattle (or any other tech hub for that matter), you really should be charging by the week. I've noticed through my own experiences that clients can get super micro-managey around here on hourly pay and try to renegotiate discounts if you're not doing something that's strictly "work". Weekly billing takes care of this as they're less likely to argue over the specifics of each day as long as you're making good progress. As for pricing, seek around $5500/week. This is roughly $130/hr x 40 hours, plus an extra $300 for "crunch time insurance". Again, I don't anticipate clients being picky about this weekly fee as long as you're meeting their needs. Heck, you could probably knock off 4-5 hours a week (eg Friday afternoons off) and still be able to charge this if you were making good progress. Lastly, since I'm assuming you're contracting, make sure that you're making the decisions about where you're working, what hardware/software you're using to write the actual code, etc. If a company wants you to work in their office on their machines as a condition of a contract, you risk losing your independent contractor status (and the business risks getting fined for avoiding L/I insurance by "subcontracting-but-not-really"). Hope this helps! Don't stress too much, it's summer in the PNW!
