I worked for more than 3 years with Primetime and Primetime-PX in 45nm and 28nm nodes. I used in a design flow that started iterating with Verilog RTL and ended with a placed and routed block, closing timing and power specs. I have also experience in other tools and older nodes, such as 180nm using qflow and OpenSTA.
I would like to hear how can I help you with your design, and we can arrange deliver time and the bid amound also.
Best regards,
