180 gallon fish tank

[Tknowles]

Good evening, I was wondering the same as the guy who posted previously. I want a 180 wih a 2ft depth and a 6ft length. I would like a wrought iron stand and a top with hood as well. What would be the best means about doing this? Should I get someone to build it? Also how much roughly should I expect to pay. I want the most cost-effective tank and accessories.
Thanks in advance for your help.
