Is it really that simple? I thought it had to be power washed with some special chemical and sealed and then painted. If it's as simple as you say, I think we can do it ourselves!
Power washing the floor is hog wash

AND IMO etching is unnecessary overkill that is a waste of time. Besides, power washing the basement floor or even washing it can ad huge amounts of moisture into the home and that can be an issue with hardwood floors.
Paints these days are all latex based and rollers and brushes are not very expensive. If you have lots of stuff in the basement then you will need to do this one section at a time. Sweep the area first. Make sure you sweep everything, even around the perimeter of the floor and around equipment. If you want, to really keep dust down then use a "sweeping compound" from Home Depot. Its cheap. See link below.

Then, with a paint brush - paint around the perimeter of the floor and around equipment. PLEASE - don't slop paint on your equipment.
Then, with an appropriate roller ( ask at the store ) start rolling out paint. BTW, if you do not finish the whole floor then don't bother trying to wash the roller. Just make sure it is fairly dry, wrap it in a couple plastic bags and freeze it until you need it again OR, just throw it out and use a new one next time.
You will be finished in no time.
Remember, what ever you do - pick a low luster paint and do not choose an ugly grey colour. My concrete floor is a light beige colour and it looks great.
BTW, painting your basement floor will NOT void any warranties on your home so ignore the builder if they suggest you wait. The sooner you are living in a clean dust free environment the better.
Use a good concrete paint. I used BEHR Porch and Patio Paint from Home Depot.
