I am not local to you, but perhaps I can help with the toroid winding.
They are not difficult - some may regard them as 'tedious', but they are
not difficult. Just remember 2 things - 1) count correctly, a wire
through the center of the core is a turn - if the wire makes a full wrap
around the core, that is two turns. 2) PUSH the wire through the center
of the core - it is better than trying to pull the wire through - that
is especially important with the ferrite cores which may have sharp
edges and can scrape the insulation from the wire. Oh yes, form the
wire against the *outside* of the core on each turn to make a nice tight
winding.
If there are a lot of turns on the toroid, start in the middle of the
wire and wind half the turns, then flip it over and wind the second half.
All toroids for Elecraft products are wound in a 'clockwise; direction -
if you wind the turns in the wrong way, the toroids will work, but will
not fit the hole pattern correctly. If you hold the core in your right
hand, the turns are formed by pushing the wire from top to bottom, but
if you choose to hold the core in your left hand, then push the wore
upward through the hole to produce the correct winding sense.
Tin the leads using the 'solder blob' method - use a high heat to make
it easier and tin right up to the core - the cores are not conductive.
The tinned leads should look bright and shiny.

hello,
is there possibly an elmer for the k2 near me? would like to sit down
and possibly get help with assembly. i am at page 60 in the manual but i
am kinda iffy on my torrid winding. i am planning on buying the
pre-wound torrids in the near future. i guess that is an art. will
gladly pay for your time. it is not the fact that the list has not
helped, i am just a hands on kinda guy, i guess.
best 73 and any help appreciated.
