Metal Buildings, best company to use, also wood construction ?s

I work with telco/bldg wiring all day and I hate metal buildings. There is no way to secure comm wire to the structure without driving a screw into it and I dont do that because of rust issues. If you got conduit, great, run it everywhere you need electricity or data, otherwise go wireless. I know this is petty for a garage but I do plenty of commercial garages made of metal and their comm wiring is always ratty. If you do go metal with all its advantages, put up cheap MDF 4X8 panels inside. Makes it easy to attach stuff, ie shelving, sub panels, Mopar pictures...etc. Also has an insulative quality as well as sound deadener. I'd trade my attached 2.5 garage for some of y'alls land! Concrete floor a must, then peel and stick tile for sweeping ease and eazy spill cleanup. asphalt is damaged by floor jacks and petroleum leaks, dirt is just 3rd world.
If you go wood, use concrete pillars as bases for all support wood joists. Subteranian termites use bare wood in dirt as elevator shafts to get to your structure. only termite damage I had in my raised foundation house was where the P/O supported the fireplace with bare wood 4X4s directly into the ground. Used a bottle jack and a sawzall to replace all 6 with cement pilings: jack support, cut off termite bottom, bolt new piling under existing good wood. F U termites!
