small lathe job

Anyone with a lathe that could machine some parts for a price?
I have planetary gearboxes that need bore reducers for the stepper motor shafts. I need split reducers like these:https://sdp-si.com/eStore/Catalog/Group/393
I need 2 no. with OD19 mm / ID14 mm, and 1 no. with OD 20.5mm/ID 14mm.
The one's I linked to are alu, but steel would be ideal. Anyone who could machine these would be doing me a huge favour, and of course I'm happy to pay a fair fee for time, materials and postage. Drawing of required parts now attached.

here's a drawing of the required parts.http://www.mycncuk.com/attachment.ph...id=14261&stc=1
