Good choice of spot mics for spotting small strings and brass sections

[TEMAS]

I am mostly a composer and I am quite excited by a couple of commissions coming up next year, which will hopefully allow me the budget to include a few days with a small string section and a small brass section (probably quartets or quintets).

I have no experience at recording either of these, but the objective will be to stack several recordings and blend with VSL samples and maybe synths to create a large orchestral movie soundtrack.

The recordings will most likely take place at my small home studio; the live room is about 9' x 10' and very dead. I know a lot of you experienced engineers would be comfortable recording the strings and brass (seperately) without spot mics and just a stereo pair, but I definately want options when it comes to mixing stage.

My knowledge of mics and mic techniques is very limited; acoustic guitar is my most recorded instrument. For that a find I get most of what I want with a Brauner Phantom AE placed about 4' above the guitar and a close mic pointing at the neck (8th-14th fret). With the close mic though, the problem I have is that everything sounds really 'boomy' if the mic points anywhere near the body of the guitar and I'm worried that this will be the problem I'll have with spotting the strings. Could I use dynamic mics for this? Where should I place the spots in relation to the instruments and where should I place the players in the room?

Currently I have (don't laugh), a pair of C451B's, the Brauner Phantom, and a bunch of dynamics - Beta 57's, Heil PR30, D112, etc. So I'm looking into buying some new mics and I guess I'll maybe have $3,000 [edit: lets make it $4,000], possibly more, to spend. And I would consider selling the C451Bs, which would give me another $600 or so.

I'm all ears. Thanks in advance.
