Need Help!!!!! Designing a circuit for a 7 Segment LED counter to display your student number (07354855)

The Problem:
Design a circuit to take a binary input and display a number on the counter. The counter needs to display the numbers 0 followed by 7 to indicate the year the coursework was done. Then this will be followed by your student number (person number). This will mean that everybody will have a unique problem to solve as no two students have the same student number. So if your student number was 123456 then your counter would need to display 07123456.

Each of the wires on the counter below corresponds to a segment in the counter. If the wires on the counter were labelled A to G from left to right then wires relate to the segments as follows:

Build a circuit using only AND, OR, NOT, NAND and NOR logic gates to simulate the counter. You should use 3 sequencers or bit generators in your circuit as input. Draw your circuit using Digital Works 95. The numbers should change automatically without any user input.

It's your school project, you're supposed to do the work.

It is a University assignment but I am struggling (who said being a mature student would be easy)

I have got as far as the first row of AND gates but cannot seem to get the right gates to connect to the LED display to generate the required sequence of numbers

ok bro here is the circuit. when u give the input of (000 001 010 011 100 101 110 111) from the sequencer. It respectively displays 07354855
