Not easy building up a nice bike from scratch using vintage Campagnolo for £600-700.
The asking prices on eBay are getting laughable, a great deal of the stuff is only fit for the tip and almost everything that is genuinely nice is priced for lottery winners only.
Personally I've stopped using old components, I buy an old frameset but use a brand new groupset.
I've found that neo-retro is quicker to source, cheaper and (whisper it) works better.
Agree with the above, you could easily spend £3-400 on just wheels, a crankset and derailleur's, not to mention other pricey Campag bits like seatposts, brake levers, calipers, DT shifters, then you'll need a nice seat, handlebars, stem.. don't get me wrong if you get a frame for a steal and get lucky on some of the other parts you might be able to do it within your budget, but it won't be easy.
I looked to start building up old Italian frames as high end singlespeeds a little while ago, but upon working it all out I'd have needed to get over a grand for each build to make it worthwhile due to the cost of some of the nicer second hand parts.
Your best options are;
A. buy a slightly tatty full bike for restoration
B. buy a full bike which has all the components you would like, but on a not so desirable frame, then strip it, sell said frame to get a bit of cash back, buy an Italian frame and rebuild
Also don't be scared of jumping on Ebay.it, it is possible to pick up some bargains and many Italians speak English/are more open to shipping abroad than perhaps we are in the UK.
