Beo has a freighter, so that's one important piece solved.
Given that, you will need the following:
1. Somewhere to mine
2. Someone in a battleship/battlecruiser to kill rats
3. Miners (3 or 4) ideally in covetors/hulks - in the shorter term in ospreys :-)
4. Someone in an
orca collecting the cans and consolidating into CHA/cargo (total 70Km3) and 'every now and then' returning to station to stash and reprocess. In the shorter term, someone with a badger and cargo expander IIs will suffice.
5. Someone with perfect refinery skills to convert ore -> minerals.
6. Someone with good trade skills to ship and sell the ore (Veldspar -> Tritanium).
The exploration/Tech3 route is a good idea, and everyone's at roughly the same level.
If the corp's looking at industrial; then the more Jumpfreighter, Orca, Hulk and Rorqual pilots the better.
Also, if someone's specialising in Industry, then focus on getting datacores - ask Beo for how, he has a lot of datacore insight.
