Want to get my first suit made. Where can I get it done within a reasonable budget? More questions:

I already have a black blazer, but it's a wedding of my cousin whom I'm really close to, so it's not gonna cut it. I've decided on a charcoal gray suit, probably single breasted, as it'll be more versatile. Where in Navi Mumbai could I get it made within reasonable price? Additionally, should I get it tailored, or should I get a suit altered to my size? (I am a slightly short man, 5'6", average build, so regular suits might be a bit too large). What pattern or material should I it in? Any suiting help will be heavily appreciated!
