Offering goods/services on finance - Sign Making

[sickrabbit]

We are a small but mighty sign-making business and deal with all sorts of clients from a man with a van through local council, universities all the way to high street brands. For obvious reasons we prefer the later and have them coming back for more on 30 days credit account basis.
The problematic ones are the mid-size companies and startups who want our goods/services but never have enough left to get a decent spec. We have been looking for a finance broker to partner with in order to offer finance in order to make our offering more affordable.

Could anyone recommend anyone?

Did anyone used creditdigital (we have been approached recently and it all sounds ok but no reviews anywhere).

Thanks

Sick
