I got my current job by doing a 3 day consulting for my boss over the weekend. I took 1 day off work on a Friday and we worked on Saturday and Sunday too. At the end of the day on Sunday he made me a job offer (note: I was not looking for a FT job, I was about to leave my previous job because of an upcoming move and hoped I would be regularly consulting for him afterwards).3 days, if you think the investment can be worth it, is doable, 3 weeks...well, that's a whole different matter.
