Help with Moving Company to Jeju

Hi Everyone

We are moving from Suwon to Jeju at the end of February and need to find someone to move our last few items that cannot be sent via the Post Office.

2 x computer monitors, 1 TV, 1 Small chest freezer and 1 rowing machine.

We have been quoted 1.2M Won by a company but I find that to be ridiculous?

Am I just completely naïve about the prices Or can someone recommend someone reliable and well priced.

Thank you in advance
