framing advice

i need some advice on framing. i just acquired 4 paintings/drawings (two singles and a diptych) that will need to be matted and framed. i have used joann's but never have used michael's. my usual m.o. is to cobble together mats and frames from various sources (dick blick, target, resale shops, etc.) and do it myself. but in this case, it's time to call in the professionals, partly because they are all odd sizes. what are your favorite resources?
