bro it sounds like your going about this the wrong way, which is really counter productive because if you speak like this in your own community then pretty soon you'll get a rep and that will make marrying young even harder for you.
ok it works like this...
you here of a family who has a sister with the right qualities in a wife, then you contact her wali (almost always father) and ask to arrange a meeting.
at this meeting you can sit down and discuss with the girl about marriage, what you both want out of life, the father will be there and will almost certainly have 5001 questions for you as well.
then after this you all go away and make a discussion on whether you want the nikkah to go ahead, if you havent made up your mind on the first meeting it is acceptable to ask to meet again as long as this isnt done too often.
so if you are looking at the masjid as a place to pick up girls, to free mix, chat to a few and see which ones you like then really this is wrong and isnt going to help you find a pious wife.
you should be using the masjid to ask the brothers there and the imam if they know of any practicing sisters, firm upon the deen and then to maybe ask the imam to go ask the girls father to speak to you if you are too shy to do this yourself.
