PLEASE HELP>> A Logo for a Modern Luxury Real Estate Company in Boston

This is what Greenville Real Estate Group ( no text necessary ) was looking for in their logo design

The company's name is Greenville Real Estate Group. We are looking for a modern take on our current real estate logo. We want to preserve as much as possible. The name of the company doesn't need to be on the logo. We want to keep the castle, which was hand drawn by the initial owner of the company. The castle may be altered and brought into 3-dimensions. The main color of the company is green and yellowish gold. We want a logo that shows that we manage and develop luxury apartments. A logo that shows we build modern day castles. The circle logo attached below has a more updated version of the castle. The updated circle logo seems very flat and dull. We want something that flows but also pops out. In addition, this is a professional business so please keep the fonts serious: no curssive or elongated text. I know this is a lot to ask but it is very open-ended. Thank you for your time. Read more
