Would photoshop be my best option?

I need to superimpose various decorations, signs, and awnings on pictures of homes and business, I was told that photoshop is the way to go but what about the decor and signs? Would I create them, can this be done with photoshop, is there a picture library I would upload to the pc to achieve this?

Photoshop would be your best bet because it has abilities to set perspective, vanishing point and so on that the others recommended don't. This allows you to take, for example, a design you want to superimpose on the side of a building, but it's the side that doesn't face you (so it is not flat). You will be able to distort/shape the design to fit the perspective of the building's side.

As for decorations, designs, signs, etc. You can make them yourself, you can use various brushes to build designs from, you can create patterns, you can add textures, etc. There are a bunch of things that come with Photoshop, there are also lots of add-on packages you can buy, and there are lots and lots of cool free brushes, patterns, textures etc. you can download from various sites on the Internet.

Photoshop does have a learning curve, but you can also (1) get a number of excellent books on it [some of which are geared towards learning a specific thing. (2) find lots of excellent tutorials on the internet, many of them are free. These include video tutorials (often in the form of video podcasts).
