I have a bard, and I had kind of a weird idea. Would it be possible, and how much would it cost, for him to obtain or make a 6-string guitar with the following spells imbued on strings made from magic:

Red String: Dancing Lights
Orange String: Flare
Yellow String: Shocking Grasp w/5 ft. range.
Green String: Acid Splash
Blue String: Ray of Frost
Purple String: Mage Hand

If possible, I'd like to get prices for 3/day on the spells and at-will. The guitar would do nothing else but provide an instrument and alternate means of amplification, as well as a cool way to fit playing Santana into our gaming sessions.
