I asked for a escrow and did not reply

Apologies, just saw I had PMs unread. The notifications didn't really get my attention.
Happy to use escrow, depending on who pays and how much it costs. Whose responsibility is it normally to pay for escrow? The person with $ or BTC?
I will not send first without escrow for people of similar/lesser activity.
Sorry about any delay, I have to wait 360 seconds between posts/PMs.
