Buying an individual contractor is exceedingly simple. For the buyer, the steps are as follows:

• Agreeing a resource specification
• Viewing a small selection of CVs
• Interviewing two or three candidates
• Making an offer
• Agreeing terms
• Signing a contract

The price agreed is "all in" which means there are no hidden charges. We make a profit from the difference between the contractors pay rate and the client charge rate. (See Contract Margins for explanation).  
Of course, we have professional indemnity insurance too.
