I plan to seed a nice amount of published adventures throughout the Southlands (it is, after all, a sandbox campaign), and the first publisher I looked at was Goodman Games.
Admittedly, most of what I have in PDF (and on CD for the first 8 adventures) or print is for D20 / 3x. Still, they are old school in feel and easy enough to strip of their 3x'isms.
Regretfully, my boxed set of the Known Realms is sitting in storage, but I may just break that out of the Southlands get to small for the party (or just move them on to Blackmarsh, who knows). My boxed set of DCC 51, Castle Whiterock, is sitting under my desk. I don't see my players looking to spend that much time in one dungeon at this point.
So, I went through Goodman's RPGNow listings and found the low level adventures, most of which I have (and will need to skim to see which ones are applicable). I'll gladly take any feedback or thoughts you might have. Next, I'll go through he three volumes of adventures in hardback from Expeditious Retreat Press and find their low level gems (as they use OSRIC, conversion to S&W is even easier).

41 - The Lost Arrows of Aristemis - Levels 1-3
44 - Dreaming Caverns of the Duergar - Levels 1-3

A large selection to pick through, I know, but I value the input of my readers. I am looking for the cream of the crop (and saying "Just use +Harley Stroh 's stuff" might be valid, but I've already used it, so you need a different reason ;)
