If the item has daily uses, its better off as a command-activated item. Thats spell level x caster level x 1800. So 2x3x1800, or 10,800gp. For only 3/day, that is 6,480gp.
You also forgot the expensive material component (25gp). As the item has a daily limit on uses, you must include the expensive component as if the item had 50 charges. So 50 x 25gp = 1,250gp.
The item would therefore total 7,730gp, and could cast Consecrate 3/day at caster level 3.
