There is a company that I would love to work for hiring right now, but they are only taking resumes online. They don't provide a phone number, email address, nothing. Just a way to send your resume and cover letter. I have already sent mine but normally I would call to check on the status, apply again a few weeks later if it is one of those slow hiring processes, etc.

If the only way I can get a hold of them is by resending my resume and cover letter, would it be OK to revise the cover letter stating my interest in the job and further describing my qualifications, or should I just not bother if they obviously don't want people directly contacting them?

Or should I just go a whole other route and get online to find the number of the human resource department, I'm sure I could find it if I tried.

This is the perfect job for me, would allow me to pay for school, so I am REALLY needing this.
