This particular approach is via a spam, and seems to be a deceptive way of offering cheap Indian contractors to companies. India is very much a centre for spam because of very lax laws, in this case "Mike Cahil" is offering to fill roles in a variety of fields, but why would you want to do business with a spammer in any case? Remember the Boulder Pledge.
Originating IP is 18.104.22.168, a subscriber to TATA Communications in India. The netblock is widely listed as being very spammy. A poke around at blacklists indicates that 22.214.171.124/16 is a real spam sewer, and strict mail administrators could consider blocking the entire lot.
