CD4000/74HC logic for moving a device with emergency brake

Based on the the CD4000 and 74HC-series integrated circuits (and perhaps the 555 timer), I need a schematic that implements the following logic (in general):

1) Move a motor (lift) up or down for a predefined time (in seconds)

2) Time could be configured via 8-stage DIP switch

3) An emergency break should also be included (either in Normal Open or Normal Close manner). It should trigger reset to the time and toggle the direction of the next movement.

4) Start condition should be enabled as series of 3 square pulses.

Expected ICs to be involved include:

NE555P - Timer 555 (at ~2Hz, used as Clock for the entire circuit)

CD4020BE - 14-STAGE BINARY/RIPPLE COUNTER

CD4040BE - 12BIT BIN RIPPL COUNTER

CD4060BE - 14-STAGE COUNTER/DIVIDER AND OSCILLATOR

CD4013BE - 2 D-TYPE FLIP-FLOP

CD4093BE - 4x2-INP NAND SCHMITT TRIGGER

CD4081BE - QUAD 2-INPUT AND GATE

CD4021BE - 8-STAGE STATIC SHIFT REGISTER

74HCT109 - 2 J-K FLIP-FLOPS WITH PRESET AND CLEAR

SN74HCT00N - 4x2-INP NAND

SN74HCT04N - 6 INVERTER

CD4001BE - 4 x 2 INP NOR

Note: Please stick to them because of the availability in our region.

Questions, suggestions and recommendations are always welcome. I can also help the freelancer with my knowledge in case you require assitance from my side (this will not affect the negotiated payment). ;)

I need a prototype as an idea (on a breadboard). PCB design is not mandatory.
