No recommendations as I didn't like the tailor I went to in Hanoi.
However, to answer the other parts of your question. The cost depends on the quality of fabric you choose, on top of the tailor fee (i.e. you can choose to purchase fabric at another place, but who has the time) - I've paid $250USD or so, but I was choosing the lightest fabric they had, which was, how fittingly for the shop, also the most expensive.
And yes, you can get wool suits. All the suits I've seen in the tailor shops I've been to were either wool or linen. No silk suits, as I recall, so no worries about that.

Two things about tailors and suits:
1. Bring one of your own suits and let the tailor copy the style. This is usually the fastest way to get things done and to make sure you like the style.
2. Don't get lured in by labels: Even if the label on the fabric says "Super 120s, Cashmere" it is usually neither a 120s (or whatever) nor Cashmere (but you can see that right away).
