Question Need Pricing for Custom 4x6 Glossy Prints – 60 Unique Files!

[siphon56]

I am looking to print 1,260 double-sided 4x6 horizontal cards on 14pt cardstock with gloss printing on both sides, consisting of 60 different files, with at least 20 copies per file.
Would anyone be able to help me out with this? Thanks

Checking them, thank you! Edit, update: Their support is really bad, been trying to connect with them, nothing yet.
