I've not changed my labour rates for years and have just had to revise them so this is the updated list, good news is the spokes are still the same price.
Build and true labour - £25 per wheel, if you supply spokes and rim with prepared hubs this is all you pay apart from P&P if required.
Stainless spokes with nickel brass nipples - £58 for both wheels, rear spokes are butted (Thick near hub, thin near rim) as they should be. I have both drum and disk wheel spokes.
I am quite happy for you to supply your own spokes but check the nipples fit through the rim, particularly on the rear.
(I never drill a rim for the larger nipples as this cuts the chrome and lets water in).
Hub (each) - bead blast and light polish - £15 (including brake plate).
Rim - Pattern or Genuine - email for latest prices
Front bearings £3.50, Rear £5.50 (inc sprocket carrier).
P&P around £12 single wheel, £18 pair inc insurance.
Rim tapes, tubes and tyres also available.
I think that covers most of it but they are your wheels and your budget so I offer a personalised service, feel free to ask any questions.
