I have spent hours making specific resumes and cover letters to highlight my skills
Question, do you have a LinkedIn profile? Do your resumes and cover letters reflect what is written on your profile?
Potential employers / agencies will definitely look at your LinkedIn profile, if you pass the resume scan phase.
Be sure that there is no information on your resumes that conflicts with what is written on your profile or any other online resumes you may have.
If you haven't already, Google yourself.
