You’re welcome. We’re all a little intimidated by the ATF. But the reality is that they have to grant you the license unless there’s something to rectify, and when you fix the issue they’ll grant you the license. Then it’s just record keeping, which for things like what you want to do, it should be fairly straight forward. The Jobox in the shed you mention should be fine as long you meet comply with the construction requirements and the table of distances.
We’ve helped quite a few folks get their Type 20 or 50 Licenses, we’re fans of everyone getting their Type 20 even if they don’t have Type 1-2 Storage since it just simplifies things. You don’t need Type 1-2 Storage to get a Type 20 license, you just wouldn’t be able to buy/store high explosive, eg. - flash, since you don’t have the storage.
We’ll help you fill out your ATF license application, and you can always call or email the FELC with any questions, they’re actually quite helpful.

For PAT Events we pull Texas State TDI Fire Marshall Permits with insurance, with FPO’s as named Leads on the Permit, and Member-Builders are covered under the PAT State Permit for shooting and our ATF Type 20-50 Licenses allow us to have build materials. The reality is if you have commercial 1.3G effects, you’re legally required to shoot them in Texas within a Permitted display. Only firms with Distributor Licenses($1700/annually) can launch 1.3G without Permits, for “testing” purposes.
Hope that helps a bit. Let us know if you have more questions.
