homemade car lifts

So ive been researching on how to wire up a garage. (im no electrician) so in all that im looking into the future of getting a lift and i want to run 220v wiring just for that. so in all that ive been needing quicker ways to do oil changes just as many of my customers have been coming to me more and more for that. along with other repairs but i use a floor jack and also have ramps but mine are built to lift trucks up higher.
so i have some ideas to make a rotating lift that you drive on and it rolls up flat and safely lifts it up higher for oil changes and inspections , again many ideas flowing around in my head so i decided to hit the net and see what people have come up with so i found this one and was wondering what people think

UP and COMING

Hey guys hows it going. im currently looking into getting a junkyard gm ls 4.8l v8  and making it boosted with a Turbo. single turbo as far as budget goes and currently sourcing a build car to put it in. im also replacing my parts runner truck with a 4 wheel drive one as well its all in whats needed in the future and with whats actually in the budget. so the by next year projects are a ls motor build, new car to build. mr2 complete. Then in the grand scheme of things im updating my shop and this will be hard to do as im limited with funds.
   In all its all i would need is money as many of us do. Im excited for the changes and cant wait for others as well.  New car hauler trailer being restored and constructed for more business and scrapping capabilities.
Thanks for reading . keep your projects running
