Selling things online/consignment??

Does anyone know of any place I can sell baby clothing for a girl?? I'm 35.5 weeks pregnant with a boy and I just had a baby shower a few weeks ago but didn't get nearly what I was hoping for our son. Not that that was the sole purpose but we were expecting about 130 guests that all RSVP'D and said they were going but only about 35 people came; we both have huge families and tons of friends. We honestly weren't going to have a shower but we were convinced into it by most of the guests that no-showed, because they said a shower was necessary since we were having a boy this time! It was very costly to have the shower but since we figured we'd have the attendance it wasn't a concern. I could've honestly bought everything I needed had I not done the shower but since that money is long gone, there's no use in crying about it. I ended up putting the rest of what we needed on layaway at babies r us but my due date is in 4 weeks and although I can afford it over time. I can't guarantee coming up with $1,300 in just about 4 weeks, and that's hoping I don't give birth earlier. Anywho here's the real question. Does anyone know of any places in NYC or any websites other than eBay that I could sell all of the pink and girly things I kept from my daughter's younger years like clothing, stroller, bouncer and stuff?? I didn't want to part with it at first in case We had another girl but considering what happened I feel like that's the only thing I can do to come up with the $ we need faster.
