Note: You do NOT need power or control just for salvage racks. You can make a 2-room base, just the entrance and 9 storage racks crammed into the 2x2 workspace, for 235k prestige. You can easily get that by just having 12 toons in your supergroup, each of whom grant 20k in "starter" funds.
Of course that only gets you salvage storage. The enhancement table is 95k, iirc., so if you really want that, you can pad up to 15 members, giving you 300k in starter funds, and go with 7 salvage racks, 1 enhancement table, and one 2x2 workshop room.
That's probably the best way to get started, then coalition with another group that has all the transporters in place, so you don't have to spend your money on that. If you are on "Justice", I'd be happy to coalition you to "Pistol-Packing Grannies"... our base is maxxed out for everything except "raids," which don't exist.
