With regard to wooden ramps, for a long lasting one I would go for at least 12mm maring ply,18 would be my ideal choice but the strengh is in the sub structure, take a look at TEX's ramp, all the weight is on the  vertical uprights beneath the ramp it self .top it off with a bit of roofing felt so its not slippy when wet......I do believe ive just done  FOCU's first risk assessment  :lol

Do you think he needs a handrail as well?....don't want him falling off!
