4 bph - 2 Liverpools and 2 Southport (375 and 385).
Ah, cheers, I'd missed that the latter was under two different numbers.
As mentioned above I've "studied" Ormskirk to Skem in quite some depth as a bit of a childhood "dream", but it isn't a feasible one and wouldn't even be somewhere like Switzerland (though I don't doubt they'd build the scheme under consideration here, i.e. to Kirkby).
I must admit, though, even absent integrated transport I'm surprised a faster bus service via the M58 isn't viable. There's already a half hourly 55 Old Roan to Liverpool (half hourly right up to the last service at 2319) which could easily be extended to Skem by adding a couple of buses to the 4 that currently appear to be used. Off peak it's 43 minutes to Old Roan, you could probably do Skem within the hour, which would actually be reasonably competitive with a change at Maghull North (25 minutes in) plus a bus from Skem plus wait time, and would still be a single seat ride (and £2 under the bus fare proposals). Peak time it'd be much slower though.
Via Ormskirk on the 311 it's an hour and a half, which is just too off-putting. I get that that basically provides a service "for free" in a manner of the likes of Liverpool-Norwich, i.e. joining up the existing Liverpool-Ormskirk and Ormskirk-Skem services (the latter used to be a "Little White Buses"* operation in addition to the "big buses" on the Southport-Wigan, and the 311 was just Liverpool-Ormskirk, fairly pointlessly duplicating the railway for a fair bit of the run but also serving places away from it e.g. Lydiate and the southern end of Town Green/Holt Green, plus being useful for Lancashire bus-only passholders), but it's just way too slow to in any way compete with the car, even given expensive parking in Liverpool, or driving to Maghull North.
* Classic post-dereg minibus operation - a bit about it on this specific route here. Later they were taken over by pre-Arriva (Drawlane) North Western and many routes were withdrawn, but this one stuck.

Lancashire independent Northway Little White Buses has launched an attack on the Ormskirk-Skelmersdale trunk route operated by Drawlane subsidiary North Western. LWB began operations with a week's free travel on the route, and is now undercutting the North Western fares.
LWB has just increased its minibus fleet by two vehicles to 12 and promises to develop a larger network in Ormskirk, but says it considers taxis to be its main rivals.
Liverpool-based Northway ran coaches prior to deregulation but has now completely swung over to service work. LWB has competed against North Western minibuses since deregulation.
