You can do those yourself its very simple all you need is a seal driver, fork seals, dust wiper and fork bushings.
Do you have a owners manual? If not get a clymer manual.
You can save a lot of cash by doing these thing's yourself and as for gold valves. Just buy them and install them yourself. they come with shim instructions (so i am told).
If you don't have time to do it, go local.
here is the link to the manual http://clymer.com/Book.aspx?bid=559&...hock+1976-1984
