So you looking at about 5 1/2 sq.ft. of area.
and about 31 cu.ft. of volume.
Everything will be overestimated in cost.
You gonna need at least 3 CPU fans for exhaust out the back. There is a how to by brother grunt in the DIY section. I'd say 30 bucks for those.
5 sq.ft. will need about 50W per sq. ft. of HID lighting. We'll go with an HPS. so you will need a 250W HPS for that. Econo-250W High Pressure Sodium $95.00 + shipping.

Seeds I seperate in the cost.
www.seedboutique.com I'd go with the Nirvana line @ 15 bucks a pack. Those I recommend for NEWBs opposed to the more expensive ones.
This in theory should produce at least 5 ounces of bud for you.
I would recommend making a veg. Cabinet to keep a female and take cutting from her and root them. Not much is need for a veg. cab. Just check out Brother Grunts Grow journals. He has a few set-ups you can get ideas from. And make them for under 50 bucks.
The fert/soil list I gave you is just one of the many re-sellers. You alos do not have to use Fox Farms. A lot of folks have had great success using there product.
Edit:
The white inerior should be fine.
Also check this thread and do a lot of reading before planting your first seed.
