Getting from Khao Sok to Bang Saphan, Thailand by public transport

Travelling as a family of four, aiming to get from Khao Sok National Park to a hotel near Bang Saphan on Jan 22 2017. Have tried several options but none brings me there. Have tried to reach the hotel over the booking page and per email for help, got no response for a week.

Almost all the bus operator pages as well as the national railways page are virtually unusable for me as they don't offer a working English version. You can switch the language to English but the travel data is still in Thai.

Tried the usable pages:
https://12go.asia
http://www.busonlineticket.co.th/
http://www.greenbusthailand.com/
https://www.rome2rio.com

The most successful dead end I have reached so far is to find a green bus connection from Phuket to Chiang Mai / Chiang Rai. However both are overnight buses with no stop in Bang Saphan and it is entirely unclear whether I could join in Ban Ta Khun and exit in Bang Saphan and whether/how much the partial ride would be cheaper than the whole thing:

The dreaded fallback option would be a minibus/taxi combo for approx 10,000 Baht.

Is there a way to make this journey by bus/es and/or train/s?
