So you have to settle for us volunteers. I assume the price you are talking about is $1,000. I can't really help you with your question because you don't really provide any information. Are you looking just for the railing, or the entire railing and balluster combination? Does the aluminum bolt directly to the stair treads or does it curve 90 degrees and bolt to the stringers? How many stairs are we talking about?
We can't see the situation, so you have to be painfully descriptive here.
One suggestion I can make is to download Copernic at http://www.copernic.com and then use it to search the internet for "bannisters" "railings" or "ballusters".
