Here is the sentence. It's from a show called midnight diner, its right at the beginning. It's like an intro that plays at the beginning of every episode. I kinda get the gist of what it says but these two specific words confuse me.
あとは勝手に注文してくれりゃあ、できるもんなら作るよってのが俺の営業方針さ。
Any help is appreciated. Have a nice day.
