Getting to Taxco
 

I know Ado goes but do any other lines make the route? Ado's schedule makes things a bit hard, limited schedule and bad times.

From where ?

Oops it seems I lwft out a vital piece of info. I'd be heading out from CdMx. It doesnt matter what terminal I leave out of. Just trying to find an option with more than a few trips leaving CdMx.

looks like these two do: Daily 10-hour tour to Taxco departing from Mexico City (wayak.mx)
Autobuses AERS Costaline | Compra tus boletos de autobús

also the first is a tour - but I am sure it is no problem ot take one there and then a day or two later take another back...

Also, consider the Red Arrow bus - Destinos (flecharoja.com.mx)

you might also consider gong from Mex to Toluca and then catching a bus from Toluca to Taxco.
