Garden design help needed

Garden design help needed, I need an experienced garden designer to help with the final part of my garden project. The property has already had significant hardscaping works completed, but I now need help to design the final part of the project including the lighting. From the main higher level sawn indian sandstone paving, steps will lead down approx 1.1m to a lower patio area. The steps will be from the same sandstone at the higher level, and I'm envisaging laying a sawn indian sandstone circle at the base, possibly with a squaring off kit. The width of the main drop is 3.4m. I think that having steps going down the full 3.4m width maybe excessive, so possibly having a rockery or another feature to add character. Another question arising is whether a circular kit will compliment the angular paving at the higher level. For the risers on the existing step to the RHS rear and the concrete to the side, i'm thinking of using a silicone render. However, any other ideas and input will be very helpful and welcome.
