[Question] Virtual Paralegal and research

As both an aspiring VA and a paralegal student I am very curious about this niche. One question I have is, if you offer virtual paralegal services how do you handle research? As a virtual paralegal should one invest in the Westlaw or Lexis online subscriptions or do you head out to the nearest law library or is it a matter of preference/convenience/affordability? I have many other questions regarding this niche, but this one seems to be in the forefront for now.

Thanks,
Anita
