12v electrical control sysem

i need a design for a control system I think i would prefer analog over digital due to project using a hf infighter so latching relays etc. I want a parts list that I can source in the us ideally on amazon. if you are us based and can build me a prototype even better. so there is a cycle start from two sources ( switch) on activation item one starts item two needs to start item three needs to be able to preset a wait period of 10 to 20 min then start. then all shut down on one of the two switches at the start of the process. There also has to be provision to run a 12 motor to run for say 30 seconds every hour from another switch once activated then the system will run until turned off. I may use a nema 23 stepper motor for this. If feasible. this is only a rough outline just trying to get a good idea of cost and time frame. thanks for looking..
