Congrats! CCNP exams are so advanced that they are requiring use of real gear.
I would start with ROUTE exam where u can use GNS3 emulator for free from gns3.net
for Switch and gear problem, there are free racks rentals out there;
There is a Sim from Boson CCNP Net Sim but it is too $$$; it costs more than real 2 switches , so it does not make sense to buy it. Besides, it does not support all switching commands.
