Recently I helped a friend of a friend find placement. It didn't take much for me to lend my network, and resources. I also steered the friend toward professional sites, and resume tips. I often do this for my professional network and family.
However, recently I've been overloaded by associates who need or want help. I hate to turn them away but I am on a job search myself, so have to stay focused.
My mentor suggested that I start thinking about a fee for service business. I checked with unemployment and if its minimum, then it won't intrude in my work status. I'd love to hear your opinions as to what is assistance and what is paid work? How do you define a service in our business of sourcing, networking, and match making?
However, I do think that pending the legality there are plenty of services you could charge for. Any type of career counseling such as resume writing or interview practice is certainly something you could charge for. There are plenty of career coaches out there who make a living advising people how to best present themselves. That said, providing some networking assistance or making an introduction is probably something you will have to do out of goodwill. It is harder to put a price tag on making an introduction for a person, and since sites like LinkedIn are built on the premise of fostering 'free' networking it may rub people the wrong way to ask money for such a favor.
Hope this helps, and best of luck on you search!
