Magento

I’m trying to develop a site that sells blinds. My main problem is that blinds are all custom made to a customer’s measurements.  So a 24x48 blind will be priced less than a 48x60.  I also need the sizes to be selectable in 1/8” increments, as well as about 6 other attributes.  So there are literally thousands of combinations.  Is there a way to do this without creating individual products for each size, because that would be extremely labor intensive.  Is there something I don’t understand?  Thanks!
