Guide to Huashan

Good morning I am interested in a private tour to Huashan mountain. Does the guide go with us up the peak in the cable car? We are not adventurous and not interested in strenuous hiking. If we go up to the west peak and find it to be a difficult hike can we decide to come down the same peak using the cable car? Another question, when is the last cable car coming down from the west peak? Can the tour be timed that we are there later in the day closer to the sunset time? Thanks
