Bricks, Masonry, Asphalt and Concrete - Mixing cement

I have never had the need in the past to lay cement, and now that i need to, I'm not sure what the mixing ratio is, (cement to water) or whatever else is used. (recommendations would be appreciated). I have to lay out a patio to a new house, (we didn't get it with the house to save over $1,300.00) however, it is something we want. please keep in mind that i have never worked with cement before, so please inform me in detail what i need to do to start all this.
thanx,
sammy

Start by leveling the playing field (read a basic how to book on masonry). After that the standing advice will be hire an experienced mason to help you with the pouring and finishing stages. (Well done, well planned, concrete project cannot be reduced to fifty words or less any more than your job could be). A minor web based overview exists here http://www.bhglive.com/homeimp/masonry.html but this is not a subsistute for the book. Afterward if you need more help repost.

First off, a patio is not a project to mix your own concrete. You will not be able to work fast enough to get a good pour. Plan on having it delivered.

Second, you will need several tools. Refer to the book mentioned in the other post.

Third - for the best look, timing is important. You just don't level and smooth and be done with it.

You can do the prep work yourself, but I'd get some bids on having the actual pour done by a pro. Prep work is digging the base, setting the forms, filling in the gravel base.
