I've had several responses and almost all automatically quote the £500 I put in the booking as my potential offer, regardless of what their usual rate is. Any that take the piss are deleted straight away.
I've had one who contacted to say she can meet, but needs to be the following month! I guess you have to give credit for her entrepreneurial efforts.
I'm down to two left (for the moment). One is very tempting but 40 minutes drive away and who says she can't make it to me (although she advertises outcalls on AW but maybe she's without car at the moment or something). I would be on her like a rat up a drainpipe but can't really manage the additional 1 1/2hrs or so travel time that would be necessary.
The other one is also very tempting, but needs to travel up from Bristol (business maybe not so good at the moment if she's wanting to come that far). I'm going to give her a no too as I'm not going to do the deposit that she has asked for.
I've had a lot of success with reverse bookings in the past and have occasionally received bids below the advertised price for a particular SP. Maybe my mistake was going in too high to begin with making me seem like a soft touch.
Oh well, there's a few days before the suggested meet so I still live in hope!
