Sorry Baggy, I don't see the link?
The easy answer is to attend a few autojumbles/boot sales and buy a used pair of ramps? One wee word of warning though, some have quite a steep run up slope. - I mean the ramped slope the wheel has to run up. If it's quite a steep one you may find the front bumper/panel of the car runs into the ramp before the wheel can run up the ramp. So I'd recommend you try them against the car before buying. I bought a couple of ramps many years ago which worked very well on my Ford Anglia, Cortina and many others of that age. As the years went by front wheel drive became popular and, because the front driveshafts are usually located behind the power unit, the front overhang got bigger. Also many modern cars have some type of air dam, or low front panel, to improve aerodynamics and this runs into many makes of ramp long before the wheel can rum up it. Mind you, if you find a really cheap pair or maybe get given a pair, you can always extend them as I did with mine. I roughly doubled the length of the run up but I'm lucky in that I have the facility to weld:

Here's the, rather rough but "strong enough", joining weld and the extra vertical brace I added:

I just used ordinary mild steel angle iron and my very basic MMA (stick) welder. Could have made it much neater if I'd broken out the MIG but I was out of shielding gas at the time.
A friend of mine made ramps out of old 4x4 fence posts glued and screwed together which were pretty robust but heavy and it took a lot of energy with a saw to cut them away for the ramped part.
Looking forward to seeing some of your ideas
