I'm a software developer. I have come across an opportunity for a short-term (less than a month) contract gig with a public university.
At my regular job I make around $35/hour plus a typical, complete benefits package.
The contract gig would only be for part-time work, around 10-15 hours a week, and would last for about two and a half weeks. This is my first time contracting and I have no good idea of what I should ask for in my proposal. I was thinking around $20-25 per hour. I talked to a friend who is also a software developer, who talked to a bunch of his co-workers, and they tried to convince me that I should ask for way more, like anything from $35-70 per hour.
Are there guidelines for this type of situation?
