The grinder can be rented for not too bad of a price.
The epoxy is easy to DIY. I would invest in an 18" roller to do it.
I did the Lowe's DIY epoxy almost 4 years ago in my garage, still looks pretty good. Cost me about $300 for 3 coats of color and 3 of clear. My garage is around 625 sq/ft. Only areas that show wear are melting into it from red hot stuff falling on the floor and an area near my welding bench that got a bunch of snowmelt and the metal dust on the floor rusted and stained the floor. Oh well though, it's a garage.
I'd guess doesn't hold up quite as well as the pro installed stuff, but they wanted about $6000 to do mine. I can redo mine a dozen times and still be ahead. I can deal with $300 every 6-7 years.
How does that racedeck hold up to welding, grinding, torch cutting, etc? Is it fire retardant?
For the HVAC in your garage, yeah, needs to be on a separate system not tied into the houses. Better off installing a window type AC or it's own unit vs killing your family.
One house I lived in just had the forced air furnace in the garage. There was some air leakage I guess and if I did anything that made fumes in the garage (painting, welding, paint stripper, etc) it would stink up the WHOLE house almost instantly. I installed CO detector in a hurry after I realized that and yes they did go off from time to time (sleezebag landlord wouldn't fix it, told us to park outside)
