Hello! <3

I'd try to work backwards from your established Stud Fee (& those of any other close available mains) as an 'Octa Dawn'
& then try to account for rare slots.

So starting from 25 GB / 25,000sb
For a *chance* at cubs with up to 8 Dawn slots

& Hexa Dawns' pricing

Determine what the "best" cub from your male would be (7-8 Dawn markings) without Special base - make that close to or above your Stud fee [Edit: Or a multiple of your stud fee, since it might take multiple attempts to get one? I think at some point players would prefer to try for their own Special-based multi-Dawn <3 ... ]
Then add a little for rare, LOTS for a Dawn-base Special (Auction) (oh my! <3333)

The market will help determine what players end up willing or able to pay, of course.
For your 8+ lovely, an Auction may be wise? If you'd rather establish true 'willing to pay' value & work from there.

If it helps, I tried using this method the other night & offered someone 20 GB for a chased NCL with 5+ Dawn <3
