Hi PhdMechEng
I don't think there is any problem/ bad issue with starting with small conference. I had also sent a 2 pages paper to a local conference from my Masters thesis. Later, I rewrite the paper by including more results, giving a different title to it, expanding it to 6 pages and sent it to an international conference. I don't think there is any problem with that. Or you can also send the paper to a larger conference straight away if you want to. Both are fine to me. Sorry if my reply doesn't help much.
