The bus journey time between Seville (Station) and Jerez de la Frontera is around 1h 25m and covers a distance of around 93 km. Operated by Transportes Generales Comes, the Seville (Station) to Jerez de la Frontera bus service departs from Sevilla and arrives in Jerez De La Frontera. Typically 10 buses run weekly, although weekend and holiday
Seville to Cadiz is about 170km (just over 100 miles) so if money is no object, I would estimate at least €200 if not more, considering the driver may wish to be paid for the possibly empty return journey. The alternative, a lot cheaper and taking probably about the same time is to take a taxi, uber or the airport bus into Seville Santa Justa OUDPtQ. 465 291 151 400 293 56 116 242 338
