If you can find a female with Enchi, something from YB complex, and something from BEL complex, you might have some tough ID's, but should get some really gorgeous colors in the OS. This girl would be a really good option for example https://www.morphmarket.com/us/c/rep...pythons/965869
If you can't afford a Clown, you probably aren't prepared to breed. Start saving up money. It takes a lot of cash before you make any back. You need to have enough to feed and house mom and dad till they are up to size and age of breeding. You need to have a rack for OS, incubator, and lots of food to feed OS till they sell. It's a large chunk of money. Plus vet funds just in case you have complications. $200 for a Clown is a drop in the bucket, I promise you. No worries though, you should take a long time to plan things out before you get started anyway, so save, save, save.
Another thing to keep in mind is that in almost any pairing, you are going to get at least some Normals or other single morph animals that aren't as popular, and they are going to be tough to sell. If you can't afford to keep them long term, you need to find some wholesaler that is willing to buy them from you, even if it's practically nothing you get from them.
