urgent. I got left and I have a family intervention Tuesday and I need this montage!

I have a series of mp3 and wav audios. I need a montage created. I can send the files in order with the exact times of the clips. I was paying someone and they've not responded in two days! HELP! There are some hard to hear clips but I have already paid someone thousands to enhance and clarify those. I can not do the intervention without the montage. I have been planning this for 4 months!!!
