First flip looking for outside advice

[Andrew Martin]

Hey everyone just looking for some outside opinions; I am a month in to my first flip and I'm doing the remodel myself and up until a few days ago i was working 40 hrs a week so I have not got as far as one would hope for, although I have got a significant amount accomplished. everything is completely demo'd and its time to start putting it all back together. There are definitely some times where I'm scratching my head trying to figure out what to do first and basically all the newbie stuff I guess. Anyways I am changing out the Windows and want to do it while I still have the dumpster(3+wks). I was thinking Lowe's or home depot for best price, if any one knows of a better source it would be greatly appreciated. A, when i spoke with some worker at Lowe's he took my info down and said he would give it to a higher up and they'll call me in the morning. in the midst of our brief conversation with this employee he asked if i had a license.. any advice from anyone when it regards permits, licenses, etc. would also be appreciated
