Could I get some help pricing the babies of my pair? :3 I've never bred for sales before.

Raiza (left) and Edom (right)
I plan to breed the two on Feb. 9 in order to hatch their first clutch on Valentines Day, as a sort of "Bloody Valentine" or "Bleeding Love" theme.
Both are gen 1, so if generation is a factor in deciding price, they will have gen 2 babies. I hope to have earned 1.2k gems by the 9th so I can give Edom Shimmer for a secondary as well, but because of the increased gem prices I don't think it will be easy. I'm just little under halfway there. My backup plan is to give him Seraph should I not have the gems on the 9th. Either way, the babies WILL be TG. Would there be a cost difference on their clutch if he had Shimmer and so all their babies would too as opposed to Seraph and not all have Shimmer? I just know there is an increased demand for Iri/Shim genes.
They will be bred in my own nest, Arcane, for pink eyes.
Please pm me ^^ I plan to have a thread made on FR as soon as possible.
