Re: professional help, have you tried looking at the options on a site like https://diypestcontrol.com/ ? They also have a live chat where you can speak to people who will provide advice and guidance for use of their product / pest control in general.

As for products, they have some hardcore stuff that is intended to go inside your walls, in the crawlspace, etc. a wide variety of use cases.
