Business Proposition

Hey GC!
This is not another "I want to start a headshop" threads. A little background first then I have some questions for you all.
First, my location in not set. I was thinking Austin or San Antonio.

Second, I have already estimated some costs and I have made a mock starting inventory (just paraphernalia and like-items so far.) i have each item planned out for buying and selling price, and quantity. So far just in pipes, bongs, grinders, papers, ect. It is 8,000. I did my "buy list" using many wholesale sites like srs and dejavu. It is a pretty extensive inventory with around 700 different items (with duplicates it is a lot more).

Third- I have taken a few other costs into account. I have prices my shelves and like-items at around 4000, not including installation(I'll do it myself). Also security bars over the windows and door, and cameras+dvr for around 2500. I would list the exact numbers but I'm at a colleague's house.
Although I did not price them, I estimated spending 2000 on a computer, software, monitor, keyboard, and mouse for business activities.

Around 300 for a standard cash register and another 300 for a good receipt printer.

2000 in signage and logo design.

1500 for tobacco license ( is it necessary?)

2000 for a Tv (60"), wall mount, and related cables.
And 1000 for some klipsch speakers and a receiver.

2000 for misc furniture.

And 8000 for unforeseen costs (there will be a lot of them, I am anticipating.)

So around 25,000 start up with is well within my budget. I plan on expanding my glass inventory to include more name brand prices so maybe 25,000 turns into 30,000. Anyway, it's an estimate.
The actual rent and security deposit is so variable I did not include it but I'm guessing security deposit+ first and last month's rent is around 5 grand.

I want to do this right. If there is anything you guys have to suggest then go ahead! I still have to get more stock like clothes, incense, sex toys, and other misc items.

Question time:
Is a tobacco license necessary? My research has led me both to a yes and no answer. Any thoughts?

Is 7,000 enough in stock? This is obviously not the sale value. Using MSRPs for my items, I got to around 30,000 retail value.

Is it better to buy from name brands or to do consignments?

I was thinking combing a hydro store with it to bring in more customers. First, can two stores like this be joined or should they be separate?

Liquid capital is no problem for me so I rather spend a lot of money to do it right.

If I think of anything else I will post it.
