1031 cost vs capital gains

[Matt Lenzi]

I am close to entering in contract for an investment property and I’m considering a 1031 exchange.  Most of what I know about 1031 is what I’ve read on BP and various searches.  I’m curious about how you find someone to do the exchange, and what’s a ballpark cost.  My net profit should be 50K and ideally I’d like to avoid capital gains, but not sure how much an exchange runs.  Anybody have any recommendations for an intermediary?  THANKS!
