Designer/Architect reco for converting double to single?

[Zoe V.]

Hi all,

I've been lurking here for a while, and am now ready to put an offer on a classic double with plans to convert to a single and resell. Does anyone have recommendations for a good architect or designer to help with the plans? I have a general sense of what I'd like to do, but as this will be my first project I figure it's smart to get some professional help. It's a total gut job near the Irish Channel.

Also, while we're at it, any contractor recommendations for fix and flips? I have a couple of names from when I renovated my house, but looking for someone who will do a good but cost effective/efficient job. 

Thanks in advance!

Zoe
