Taxi from Lugo to Sarria

We are arriving to Santiago just before 4pm on 17 May and plan to take the bus to Lugo. From there on as the bus to Sarria only leaves at 8pm, we thought of taking a taxi instead.
1) has anyone taken this taxi from Lugo to Sarria before? And how much would that be?
2) any other travellers who would like to ride share on this date?

We did check the timetable, but based on our time of arrival to Santiago, we will have to wait for 2 hours for the 3.5 hours train to Sarria... thus bringing us to only arrival past 9pm.
Trying to find an option via bus will take us to Lugo instead, and we are wondering if its easy to get a taxi from Lugo to Sarria and how much that will cost.
We know we can also get a taxi from Santiago direct to Sarria however that will be costly, as one quotation we have is for Euros165.
