Why do you want to "weed out sight unseen"? (NTM a PICTURE of them IS sight) You will be losing some of your best potential if you judge people on their looks. Yes you want clean cut for image but this is not the right way to do it.
Also, your best employees will be found with lots of hard work on your part weeding through many applicants. There is no "one place' to find all the good people. If there was, everyone would go there
There are new people entering the job market every day for infinite reasons, not all bad. Don't fool yourself into thinking people won't work for you because "they are all gone" people will move jobs if they have incentive usually most monetarily.
No idea what you are paying but, remember the old idiom "if you pay peanuts, you will get monkeys"
