We only have integration for dojo (and Paymentsense) at the moment. If you are a dojo reseller, you could speak to your partner manager and ask them if they are able to sign them up with Paymentsense instead - same company but the acquiring is done by First Data whereas dojo all the acquiring is done by them directly, so they decide their own level of risk based on the business type.
I would say however that if dojo are not willing to supply a terminal, you may find other card providers will be the same and they may be stuck to only using the likes of SumUp, Zettle, Square, etc. which charge a higher %.
