you quoted earlier " I'm not completely opposed to having a house in the logo, but it would need to be something different like the logo here:
http://www.phoenixmarkettrends.com "
here i present to you in my concept, a house done executed in a different creative way from the " mn " initials of your brand name.
its simple, elegant, corporate and would feel feminine as well because of its simple lines / approach.
it works well on dark background ( like at your current website, i've made sure i use colors that matches with it, very dark grey and lime green ) and also works well on off-white backgrounds for business cards and also black and white for letter heads / faxes / etc.
hope you like it.
thanks,
