salary negotiations pre contract
I have been offered a freelance telecommuting proofreading job with a US web company. I applied, they interviewed me and offered me the job, but so far I haven't responded to their offer (today).
They have offered me $US20/hr which is well below the industry standard for proofreaders, and in fact the job is more copyediting than proofreading. I'm actually not going to know exactly what will be required of me until I get my first assignment. However, they told me they believe each assignment will be about 1 - 1.5 hours work (I suspect more, but will have to see).
With the exchange rates the way they are, $20US is less in $AU so I will be making even less again. I don't believe the rate they have offered is appropriate for my experience and education. I earned $40/hr in my last job as a technical writer, which was not even freelance.
I believe the industry standard is $35/hr MINIMUM (can be much higher, but I would be prepared to accept $35). I also believe I am uniquely qualified for this job, as far as they're concerned because they are a US company who needs an Australian proofreader, I was referred to them through a friend so they didn't need to advertise, and I doubt they had anyone else lined up.
Can I negotiate? How would I do so. I am absolutely terrible at negotiating and I'm worried that they'd say "$20 or nothing, we'll find someone else." I just don't know what I should do.
