Narrative:

Exiting runway 35L at B6; we were instructed to taxi [on taxiways] B; G; J; and cross runway 29 to our ramp. After crossing [runway] 29 northbound on B; the signage is very poor/confusing. I started to roll past [taxiway] G; thinking it was a little north of where it actually is; when ground control corrected us and asked if we were able to make the turn. We had enough space to still make the turn onto [taxiway] G. Then; the only sign indicating where [taxiway] J is located is [about] 100 yards east and hard to see. Ground control sounded kind of stressed/irritated; which leads me to believe this happens a lot at this intersection.
