Please use this link it should take you to Olga,s contact information, many of us have asked her to hire odd things, me ,I needed a wheelchair for three weeks, she did the job easily.
Olga has yet to be beaten and I use her every year, she is a smashing lass, give her a call, you have nothing to loose and everything to gain.
