They were great to work with - always helpful & very responsive when issues arose during our project planning phase! There was some overlap between two projects we worked together.
We could not reach an agreement as they wanted us to pay twice what another designer had proposed (I think it was around 30%). I feel like this made them look unprofessional because we couldn't agree terms. The end result looked fantastic though, so no harm done but still felt that there should have been some professional courtesy shown by both sides.
