Find External Consultant
Finding External Consultant is not easy as on date. Here is some tips to source your external consultants.
1) An easy way to find a external consultant is enquire with your current consultant. He/She may be aware of who in their network, is ready to go extra mile by doing external consultancy after regular job. Your current external consultant can source new consultants.
2) Linked.in can be a nice place to find external consultant. Though it is not a job portal, but it is a social networking of Professionals. It has a option to say looking for full time job, consultancy and part time offer. I assume that the search of linked.in can help to filter of professional opting for consultancy or partime offers or work from offers in a specific domain.
Regular job portals does not support external consultants sourcing as on date. There is no job portals specialized in sourcing consultants resumes.
Sourcing an external consultant is easy as or tough as sourcing a Prostitute. :)
