Not sure what Ink paid for hers, but Continental is reasonably priced from what I hear and you get what you want. Thing about a custom saddle is that you get what you want and if it ain't right, send it back. Plus they have good reveiws.
You can spend the same amount on a used Bobs and might have to sacrifice what you are looking for. Look up Bobs custom saddles...they are not cheap.
The earlier Chavez saddles are good, but from what I hear their quality is/was declining so I would be cautious there.
Depending on the level of shows you plan to show at you may be able to use a cowhorse or ranch type saddle that is clean.
