We went with Rising Sun for our pool. We had good experiences with them, granted it was winter time and they dug in February so may not have been as busy, but never had any issues with quick responses to emails, quote changes, and having them come out a couple times to talk through the design.
Yes, they won't provide 3D renderings or landscape design. They are a pool installer and its up to you to figure out the rest - although they work will with their preferred sub-contractors so it was a good process overall.
I though didn't mind since I had spent the past 6 months designing the layout myself, obtaining the 3D CAD models/prints, placing the pool, spray painting the backyard with the pool/deck outlines, etc...
I feel planning is key, knowing exactly what you want, then sticking to it in order to stay on track and budget and be able to compare apples-to-apples against other builders. Good luck - its good pool weather right now!
