[Naerron]

So, I am looking for a way to work from home to keep a job while I persue grad school. Have done a little SQL work years ago, but I know most jobs in that field require or at least benefit greatly from knowledge of more languages. And I guess anothet question I have that dove tails with my original question is about entry level jobs be in website maintainer or what have you that would be good in my situation. Thanks for any help and sorry for sloppy grammar on my phone.
