Help with a strobe

Not next weekend but the week after I need to borrow or rent an Ikelite strobe and hopefully a TTL cable that fits the housing and strobe. If your willing to help me out please send me an pm. Its for a friend who is trying to see if something is worth calling an archaeologist in for to study in a sink/cave and the internal flash is not good enough to get the shot to send to him. FYI I've got the one handle model and I also need an arm setup. I can meet this person in cave country before Sat and have it back on Sunday.
Thanks
Tom
