where to produce shoulder axle/pin/shaft/dowel pins (budget, 10 pieces) ?

I would like to
- create ca. 10 shouldered pins* in order to glue gearwheels** to it
- ask you for any advice or link that may hint me towards a solution

any ideas are highly appreciated:
i already had a look at misumi, conrad, rscomponents, alibaba, ebay, amazon "small parts" …
but could not find any suitable solution.

* pin's dimensions:
                      left              center                     right
diameter 1 mm 2.5 mm 1 mm
length 2 mm 13 mm 2 mm

**made from delrin & brass.
These gearwheels are spinning at a speed of ca. 4000 rounds per minute
(my "pre-prototype" diy axle worked well with superglued-gearwheels:
A 1mm steel wire surrounded by heat-shrinked tube)
