Tailor made clothing

I have kind of a hard time finding clothes, especially pants/slacks that fit well. For that reason, I wanted to have some slacks made, about 4 or 5. I started checking with tailors that specialize in made-to-order clothes here in San Francisco and I was shocked to find out that, on average, they wanted to charge me about $200 per item!! I've never had anything tailor-made, hence my shock. Then I remembered that I am going to be in Mexico City in a couple of weeks and I could have some slacks made while there. Do you guys have any experience with tailors there? Could you recommend some? Any idea how much can I expect to pay? (I speak Spanish so I should be able to communicate with them well.)

Thanks.
