WEST U.S. -- looking for some advice to open wireless store

[kimosan]

hi,
im plannin on opening a small to midsize wireless phone store in orange county ca.
im thinking of carrying att n t-mobile as service providers.
i have doubts since the economy isnt doing so great right now.

does anyone know what the average start up expenses are?
how does the commission plan work with major carriers like att and tmobile?
does the value of the phone sold come out of my commission?
how much are the current commissions for:
single line?
family plan?
upgrades?
and i heard that theres also extra monthly bonuses if a minimum of 50, 100, ..contracts are signed

if there is also anyone out there trying to sell their store in orange county please let me know. i might be interested. also open to a partnership deal (whatever share or if someone has a good running business and would like to expand!!!!!)
