Trailers for Pontoon Boats or Prams?

[FishBS]

Does anyone know of a good source / place to buy a small utility trailer. I need 
something that can carry up to three pontoon boats  or several 10' prams. I looked at 
several at Sam's Club, but I'd like to spend a lot less then $3,000.00.
Thanks for any info you can provide. Six weeks until March 1st.
Thanks,
Brian
