I have come across some websites that offer city ready pool plans and engineering. They just need a drawing of your backyard with some measurements as well as a basic sketch and measurements of the pool you want. The cost is about $500-$600 for the plans and another $200 for the engineering. For another $200-$300 they claim to give you a list of subcontractors in your area and help guide you through the process. To list a few: Howtobuildyourownpool.com, Diypoolplans.com, Pooleng.com, Ownergrown.com. Anyone have experience with these companies before?
