I think you're getting into a very hard market. It would take an enormous amount of trust to start using such an external website. Personally, i would only consider trusting an external site if it was either owned or operated by a long-term, extremely trusted bitcointalk member, or if a long-term, extremely trusted bitcointalk member kept enough collateral from you in order to repay everybody in case you ran with the escrowed funds.
Even the most trusted users are still subjected to any scam actually. One incident was the one with master-p, i still can't judge the man for how trusted he was ever since.
If OP is talking about escrow for ICO, investors will prefer the trusted ones here in the forum or better yet on exchanges like bittrex.
