affordable health care?

i work for a small company (5 employees) so we do not have a health plan.
i don’t have health insurance, but for my own and my families sake, i should get some.

how can i get affordable coverage that i can rely on. i don’t want some healthplan where i have to single out a clinic for all my needs (i travel alot throughout the country, so it should be a plan that is accepted in most states)
plus i’ve heared about aflac as a supplement insurance that covers some basic things) ideas, suggestions?
