Justin Rhodes. He has a recipe, its one of the better "make at home" recipes, in that if you put the ingredients in to a feed calculator, it outputs nutrition data in the ranges you would anticipate for a decent to good off the shelf feed, unlike many (most!) "make at home" recipes on facebook and youtube. it also has the benefit of successful use by a lot of people over a (relatively) long period of time. So according to both theory and practice, its good.
It may not be less expensive, but it will call for some of the ingredients you list above. Once you understand why Rhodes uses the ingredients he does, you can consider potential substitutions - but the fish meal is key to the recipe's success. In a nutshell, this is it (output from the calulator I built). If you can't get high quality fish meal (near 60% protein), you can compensate in part by usuing hard winter wheat, but its not a perfect substitution by any stretch. You can play with the addition of soy meal - depending on its assay - to back out some of the fish meal as well, since its generally the most expensive ingrediet in the recipe.
Many of the published copies of recipes purporting to be Rhodes' (I don't own his book, can't say from first hand knowledge) include a vitamin/mineral premix (like Fertrell's Nutribalancer) as well, in very small quantity. (Again, caveat that the numbers below are not corrected for an "as fed" condition, which would drop these outputs roughly 10%) Lower protein fish meal will also have signifcant effect - I used 75%DM CP in the calulator, but there is good chance you will find only a 58-63% CP by weight option, which again would have slightly lower outputs.

Pasty butt is often stress related - chips that are shipped are prone to it. Heat stress can encourage it. Some feed ingredients, like oats, which are high in beta-glucans can do it. Sometimes, there are no clear causes, can be a combination of factors
@Perris has
posted some old recipes as well, I know from prior math that they output well from a feed calculator.
Recipe #1 looks like this out of the calculator, though you may have difficulty sourcing the wheat bran and middlins, and of course "Meat and Bone meal" is a term of art for a feed ingredient we aren't allowed to use anymore. You can substitute fish meal or porcine blood meal, and have a close approximation.

Hi All, this is OP husband, whom is very computer illiterate, so please bear with me. Here is the ration I have been making for a few months now and it seems to be working well. I do have a ration calculator, I was unable to post the ration on here from it so I will do it manually:
