Select a service via URL parameter

Dear support,

I have placed the booking form on a separate page, and would like to access it via one of 4 links from the pricing table on homepage. Pricing table has 4 services, so when user clicks “BOOK NOW” under one of the services, I would like to be able to send the service selection via URL parameter to the booking page, so that user doesn’t need to select it there again.

Here is the website pricing table: http://www.uniquetantra.com/#plx_pricing_section
Here is the booking page: http://www.uniquetantra.com/booking/

Something like this could work: http://www.uniquetantra.com/booking/?service=1

Maybe it is solved already? I could not find it on this forum or in docs. If so please help me out with instructions.

Thanks!
