Maybe you want to try Wirex Business. I use them and i am very satisfied with them. They may ask you some questions for the first few transaction but that's it. Your business is legal anyway, so no problem at all.
Kraken has been working great for me for long time. The verification process was easy and fast.
The good news is, AdvCash is back again, you can buy for $10K a day bitcoins if you have a veriefied account with them. That's cool and has made my live just way easier.
