Pest/termite control - recommendations needed.

Hey all, I am looking for help with termite control. I found good reviews for Samadhan and Omega Pest control, but am not sure which one to go with. The issue we are facing is a bit complicated at the moment, so wanted to ask recommendations for good termite control treatment (near gajuwaka) - would be helpful if the technicians/service are patient and understanding. Thank you!
