When it comes to keeping costs low in regards to staffing methods, the internet is the best place to turn.  Here are the top three internet staffing methods used by companies.

1) Monster and HotJobs - These two companies make up well over 80% of the entire market.  A job seeker is going to have a presence in at least one of these.  It will cost your company about $400 to place a job.  Be sure to add specific key word strings so that your job will show up in search results.

2) Craigslist - This is the alternative to spending $400 to place a job posting.  It costs $25 to place a job, and you will get immediate results from your listing.  This is ideal for entry level and admin jobs.

3) LinkedIn - If you want to conduct research for candidates, then this is the route to go.  Access to Monster resumes can easily cost $1000 per month based on total views.  You will need to set up a company page and have a strong profile for the person who is the point of contact.
