I could do it in a couple of hours.In that case the OP should offer to produce the app for $500 then pay you for 2 hours to actually write it. Everybody would win, and if you set up their system so you can handle SQL Server remotely, even that can be free too. You're right, this is definitely the way to do it.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
