Any good LEGIT sites or shops where I can send my stick to get modded?

I have a Blazblue Hori V3 SA and I’m not good at modding. This is a pretty rare stick and I don’t wanna risk destroying it. I wanna get it modded for dual use with the PS2 so I can also use it with my Wii and Saturn games. Any good reputable places I can send it to get modded that won’t rip me off? Any help is appreciated.
