It would have been a helluva lot cheaper to just get an AZ or UT CC permit. You can get both as a non-resident of the state, and they both have reciprocity with CO.
This is entirely incorrect. UT and AZ do have reciprocity, but not for non-resident licenses. Following the above advice could land you in some hot water:
CRS 18-12-213. Reciprocity
(1) A permit to carry a concealed handgun or a concealed weapon that is issued by a state that recognizes the validity of permits issued pursuant to this part 2 shall be valid in this state in all respects as a permit issued pursuant to this part 2 if the permit is issued to a person who is:
(a) Twenty-one years of age or older; and
(b) (I) A resident of the state that issued the permit, as demonstrated by the address stated on a valid picture identification that is issued by the state that issued the permit and is carried by the permit holder; or
(II) A resident of Colorado for no more than ninety days, as determined by the date of issuance on a valid picture identification issued by Colorado and carried by the permit holder.
(2) For purposes of this section, a "valid picture identification" means a driver's license or a state identification issued in lieu of a driver's license.
The statute you would be violating:
CRS 18-12-105. Unlawfully carrying a concealed weapon - unlawful possession of weapons
