Ask HN: I need a Google calendar type GUI..But how? (dont have the skills)

So people,

I am building a staff scheduling application and I really need a GUI for adding shifts and all that sort of stuff.

Google's calendar GUI is exactly what I need but I am no good at front end design, its not something i could do.

What I need to know is, what are my best options for getting my hands of a GUI like this?

Are there business's that specialize in this sort of thing? I am willing to pay the right person to get the job done.

Any info would be great! Cheers
