Crawl Space Access/Doors

I am getting ready to finish my basement. It is half basement and half crawl space. The crawl space areas are cemented and we have been storing stuff their for a couple years now. I am not sure what to use to keep access available to these crawl spaces. I plan on putting up drywall for the walls but I have no idea on how to get access to crawl spaces and also make it look nice. Someone mentioned removable panels but I do not know where to get those. I also was thinking about some kind of access door but I have been unable to find any example where to buy materials. Any help or suggestions would be much appreciated.

Thanks

 

I hope you have all the vents close off in there and insulation on all the outside walls there in the crawl space Id still put down a 6 mil poly om the slab.
Now door to it dont know what are how big you have there. But you can get a nice piece of ply wood 3/4" and hinge it on one side or make two smaller doors and hinge it on both sides for a bigger opening. Right there on the studs . then run some trim around it.
