I met with the consulting firm and they begged me to take this job. It's about a month, full-time, and they'll give me $55/hr. for it. I'm a little nervous about the level of requirements they have for the project, which in the near term involves a lot of band-aiding of a Web app, but we'll see what happens.
I told the recruiter about my concern and we agreed that I'd try it out, and I'd split if it the project scared me too much. Projects with weak requirements are notorious for failure.
The other potential issue is that, while not seeing the code, it sounds like a rewrite job, not a band-aid. I'd go as far as to say that it might be faster to rewrite it.
I guess we'll see Monday!
It doesn't really hurt you as a contractor to try it out either. It's not like there's too many long term effects to your career. $55/hr, sigh, I look forward to the day I can command that kind of salary.
