Permanency and greater magic fang
Is the x3 because he wants two claws and one bite?The cost for a single +3 Greater Magic Fang is 12x30 = 360. The cost for a single +4 Greater Magic Fang is 16x30 = 480.
The cost for a single Permanency on a single Greater Magic Fang is 11x50 = 550, plus 7500, for a total of 8050... assuming you want to go for the minimum caster level. Remember, the lower the caster level, the easier it is to dispel, so while your CL16 GMF might withstand dispels well, it's no good if the CL11 Permanency gets zapped. You'd be well-advised to find as high-level a caster as possible to cast your Permanencies.
So if you want GMF on two claws and one bite, you're looking at a minimum of 25230 for +3, or 26590 for +4, and more if you boost the CL on the Permanencies.
Of course, under 'Spellcasting Services', it notes that "If the additional costs put the spell’s total cost above 3,000 gp, that spell is not generally available." So you may have trouble finding someone to cast Permanency for hire.
