Danish Volleyball coach

We are going to Denmark from July 16th-30th ( maybe 2 to 3 times a week) and we are looking for an experienced private volleyball coach that can train our 2 teenagers (13 & 15 yrs. old) as they a they are both in power leagues here in California and we don't want them to go this long without training. As when they get back they are going into try-outs, this coach would come to our house in Farum Denmark ( we have a net in the backyard) or we are willing to drive if the coach has access to a gym/facility.
