A quick look at Ponoko suggests that a 7.1"×7.1" of 0.03"-0.04" (180mm × 180mm, 0.76mm-1.0mm), lasercut into a single mesh (so you'd use side cutters to trim the "pin" and a support tab), would cost about $200 in brass, $250 in copper. The kerf width on the laser is 0.01" (0.25mm), and minimum feature size 0.04" (1.0mm). You can certainly fit 1000 of them into one sheet, so that would be the price of the untinned blanks. Cutting them off and inspecting each (at least the pin) and tinning them would also take time, so it would not be cheap nor easy!
Could you use connector pins (crimp terminals) instead? For example, Molex 5421 series (SPOX,
3D PDF) has a 0.65mm square pin, with the lower crimp section just under 2.0mm wide when uncrimped, and are available in strips of 100 (for about ten euros per strip at Mouser). TE 170376-1 has a 0.64mm×0.7mm pin, with a narrower body. Lots of options, and since they are intended for a similar purpose (just used in a housing, instead of soldered to a board), they're well spec'd.
