Quite honestly, if this only for your personal use to have guns shipped directly to you it will not be worth it. Like has been stated you will need to send in the check for the processing fee, apply for a business permit, maintain a logbook, be available for inspections when the ATF notifies you and have adequate safety measures which usually include much better than the average home owner gun safes, an alarm system and have insurance for your firearms related business, by the time all is said and done it probably wouldn't be worth the cost just to be able to have some guns shipped to you directly.
