Hi there. I've been working with a print house from USA for more than 2 years now and I prepare them Excel Price Calculators (exactly what you need) But believe me, it is much more complicated.
Relevant Skills and Experience
Excel, VBA, Data Processing. Im not sure if you can use patterns to quote properly. So, you better build a quote calculator with the parameters (type, sheet size, thickness, color etc.)
Proposed Milestones
$2500 AUD - job done
My bid is for building the full calculator. Not for your job (which I think not the way to go) I know what print houses need. There are lots of parameters to be taken into account while quoting. So, pure pattern approach wouldnt help a lot.
Contact me if you want to discuss more. Thx!
