I don't think this is a phishing attempt, since when you go to actually apply for the job, it redirects you to "The Eleven Agency" (jobs.t11a.com), which appears to be a legitimate company despite them being hosted at 1&1 and having private registration.

Also, this company appears to be the creator of the website: http://www.chaione.com/houston_website_design_clients.shtml

The job postings are also scattered all over the different job sites (i.e. HotJobs, CareerBuilder, etc...)
