Ok, sounds good.
Then I would focus on putting your Karma into getting the decking Skills up. As the Deck mainly sets your Limits (I know, the attributes have some other advantages as well), your Skills really determine, what you can do as a Decker.
Your money can then flow into upgrading or expanding your augs. Most of the stuff you'll want will be really expensive and hard to get by. So save up for the opportunity.
Otherwise I think the concept should work fine as "on site" Decker.
PS: First thing: Get your Edge up to 3+
You'll need it...
