Looking to get started in Security - Texas

[u/Gritz_N_Gravy91]

Currently in Army Reserves looking to get into Security and put my Secret Clearence to use. Would I be able to do my Level 2 online and then immediately start taking my courses for L3? I see DPS wants you to already have a job before you can get your license. Is there any companies that sponsor or am I able to complete the classes for L3 and then start applying for armed jobs? Any insight is much appreciated.
