Do what I said and buy some heavy guage Nickel strings.
The last thing you want to do when your on a budget is to buy some custom strings. Theres no need to pay more for something you dont even need.
Nickel strings are gonna benefit you in a lot of ways:
1- they are a lot warmer sounding and in essence give out lower frequencies -which will make your drop tuned bass sound more powerful and it will sit better in the mix.. All the guitar distortions are gonna fill up the mids and the highs, you want to stay LOW in the mix (any maybe get a grit effect as a noverdub for some highs too, which will also make you stand out more)
2- Nickel strings last longer. Perfect for bassist on a budget.
I used a 'heavy' string set when I was in my old Metalcoare band, which our main influences were August Burns Red / Texas In July.
Each string was: 50, 70, 90, 110.. The brand I used (who I am actually endorsed by) do a 4 string set, similar, which is 45, 64, 85, 105, 130 which will do you just fine - trust me
