If it happens to be weeding day in your town (or you're willing to time travel a few days) please let me come weed your town if you have, say, 100+ weeds. All I ask is that you let me speak to Leif and obtain the furniture.
If anybody has a lot of weeds (say 100+) I can come help you out! The only thing I ask is that you allow me to visit Leif in your town (I won't purchase anything, however.) It must be WEEDING DAY.
