I would like to begin mining for bitcoins right away, but is there a guide?

[Zakcy]

I have my wallet set up, and I have my mining build all ready to go!

My plan is to try mining for a week, just as a test run. Does anyone know where I can start?

Thanks so much for the help

Try one of those pools at the mining subforum. Either one like abc, btcguild, and deepbit will do for non full time miners as they're a pay per share pool. Just choose the one with the lowest fees and the highest stability will do(you have to run the experiment yourself as this depends on your location, but I doubt this will be a problem).

I suggest you sign up with BitMinter
You can very easily launch their custom miner with a mouseclick.

Also give this a read, it helped me.

Be sure to join a pool to actually get some income, like http://mining.bitcoin.cz/
