ICR Transfers

In May, my elderly mother and her friend will be going to Siteler between Marmaris and Icmeler. There is no transfers included in their trip. Has anybody used ICR for tranfers as i want to book it for them as they dont want to just pick up a random taxi at Dalaman? My mum is a little concerned about the drivers and who else will be on the transfer with them and no amount of reassurance from me is helping. Can somebody put it in print for me so i can attempt to reassure them more? Are the drivers reliable in picking up etc as it will be from an apartment that is a little out of the way?
Many thanks...Simon
