Hi,
I have nearly 20 years of experience with SAP which includes many ERP and PI installations. I can install both for you on any platform (Windows/Linux/Unix) and any database (presumably you want Oracle).
My price is outside of your budget, but SAP installation is quite involved and fairly complicated process. My employer would charge this amount for 2-3 days of my work which would probably cover only the design, not even the actual installation.
Do you have a Solution Manager system to generate the installation keys and to allow the download of patches? Also, do you have any installation media?
What do you want to use it for? As the way it should be installed depends on how are you going to use the system.
Finally what configuration do you need? For this price I will be able only to perform basic technical post-installation configuration without any integration between ERP and PI.
Please let me know if you want to discuss and come to some kind of arrangement.
Thanks,
Rob
