I think that your english level is same as mine !
Your offer is very kind ! :-)
I would be pleased, but first I must think about going or not going to Surin, it may be a bit far for me, as the flight from France will take 12h, I may prefer to avoid long trips within Thailand.
Is there a train from BKK to Surin ?
(I just checked Phuket on Google : ouch ! that's very far too)
