20 Piker Triangle builders in Melbourne

Hi, I am after a Pikler triangle and ramp with some climbing rocks for my toddler. I have attached pictures for some idea and size.

If possible to build similar to the description found on instructables (titled How to Make a Collapsible Pikler Triangle) But no painting or varnish on the wood. Just raw wood. And the pivot can be slightly different (simpler) And spacing between the rungs can be a little closer, perhaps either 3.25 or 3.75 inches. Thanks! (Price includes material purchases.) Also want to add: Reversible climbing ramp/slide as in photos, approx 5 feet (150cm) long by 9.5in (24cm) wide (or 12 inch would be fine too.) with ladder pieces attached to one side as shown.

I would like x2 sets of collapsible climbing frame X2 large folding frames 1000mm high x 1150mm base x 1175mm wide Climbing rungs are 9cm X2 medium folding frames 750mm high x 860mm base x 880mm wide Climbing rungs are 9cm X2 Ramps 1.2 metre length x 45 cm wide Plywood and joinery materials must be provided and inclusive of the price Google how make it e.g. [Content Moderated]

Put together 2 x items, small cot size house bed and 1 x bridge- 20 screws only for second piece.

Pikler height to be around 80-90 cms. Need to have 7+8 climbing rods. L = 90cm W 75cm Ramp size needed 110 x 35 x 5+ If they can do rock climbing ones that will be amazing too. Need them on regular basis for my store so a good price will help us go long way.
