Halides don't have to be expensive if you build yourself a lighting hood to mount some spider reflectors in.
If you want to do cheap halides, buy 2 x 400w halides. They cover 24" each, so that means the ends of your tank will be slightly dim, just leave 6" where you don't put corals. You can buy basic m58 ballasts in cheap enclosures from a lighting wholesale store for cheap, or post here for used one. Then buy 20K XM bulbs from
www.jlaquatics.com for $85 each, and a set of 12" spider reflectors with mogul sockets. You can do this for around $400 - $450. Then your bulb replacement cost each year is $170. You can build the lighting hood out of pine or similar for cheap, and you will need some fans for cooling. So say $750 for the hood, lighting, and fans. It would be better to go with 3 x 400w or 3 x 250w for better coverage, but you can start with 2, see how it looks, and add in a 3rd any time later easily. This way you could keep anything you want in your tank, and halides look awesome.
For soft corals in a deep tank you should use PC lights, but they aren't cheap either, better to go with halides from the start IMO, save you money in the long run.
Once your tank is safe and tested, then you need to cycle your rock to establish the bacteria levels, then you can add livestock but you will need lighting (nothing fancy for fish only though) and then a skimmer, etc. Oh but of course you need to have your sump plumbed and ready to go first. You might want to look at an auto top off system too. For long term success an RODI unit such as Aquasafe are great, but I am told Calgary water is better than Edmontons because Edmonton uses chloramine, Calgary doesn't.
You will need test kits, (good ones, salifert of Seachem, not Hagen) a hydrometer or better yet a refractometer, etc. Along with your sump I would plan the refugium from the beginning. And of course you have to decide if you are going with a sand bottom or not, and what size grains, and how deep. etc. etc.
