As suggested in your other thread, this link will give you the breeding results for pretty much any combo you want to pair: http://www.worldofballpythons.com/wizard/. There is also a page on the site that lists tons of morphs and combos if you want to just play with what would work best with your BEL.
For prices on those results, you can look at market.kingsnake.com and faunaclassifieds.com.
