I want to get my entire arm tattooed. cost? time?

I plan on getting my entire arm tattooed from my shoulder down to my finger nails. I want to get a Frankenstein/ zombie/ cyborg tattoo i haven't seen anything like what I'm planning. i plan to ger it looking stitched together and rotting but also having machine/robot parts. steam-punk/terminator style. unfortunately i live an hour away from the nearest(good) tattoo parlor. and i need to know what the cost would be and how they charge(detail, per hour, etc) and how long it would take to get my entire arm tattooed everything except my arm pit and underside of my hand. all input is appreciated and of course most detail gets you the best answer and 5 stars ;D
