I see that you said the Hashkings.com domain is gonna cost over $4,500! That's insane man why not just do a different spelling or do a hyphen in there. I'm sure "Hash-kings.com" or some other variation might work and be hella cheaper.

I had a similar issue when creating my ServerLyf.com site. Serverlife and Serverlyfe were both taken and they wanted a bunch of money. I said fuck that and did a different spelling and only paid like $30 for my domain over two years ago.
