Which versions of the modules will you use -- the originals, or the super-module reprints?
If you use the super modules, T1-4, A1-4, GDQ1-7 can be a reasonable sequence (though you'll have to scale back XP awards a bit for 3E). T1 by itself would require maybe one or two more adventures before you launch into the A series -- some of the UK modules, like UK2 & UK3 (The Sentinel & The Gauntlet) could work here.
B2 Keep on the Borderlands is always a good campaign starter, as is B4, The Lost City.
You could also do the Lendore Isles series as a level 1-3 intro series; they're pretty good (L1 -- Secret of Bone Hill and L2 Assassin's Knot are free downloads at WOTC if you don't have them; the hard-to-find L3 is completely optional).
