here's the alternative and much easier strategy: mine every resource out on the map around this guy's island. then, kill off all ur probes and use just about every available food point you got into making carriers. carrier costs 6 food right? make about 24 carriers with some arbiters to recall in mass reavers once you've cleared the landing zone. even with seiged tanks, those mass reavers are bound to take out at least something on that crowded island. carriers are self-explanatory. stasis any bunched terran air units for later.
