From what I am led to believe, huntsman spiders arent dangerous to humans and tend to come inside when it is going to rain. I know they look really scary and I am the first person to run and carry on if I see one, but I think it would be unnessecary to pay for pest control.

Can you use a broom and carry them outside on that?

FWIW- I paid $300 for pest control for mice and we have a 3 b/r house. Usually they charge by square metre.
