As a startup, one thing you must learn is to minimize your cost without affecting your performance. There are lots of great freewares and free resources nowadays that their quality is very close to or even better than the paid programs.

Let me tell you what freewares and free resources you can use to replace the expensive ones.

1) Word Processing: Open Office
The Open Office is basically a free version of MS-office. I still think MS-office is a little better because I am so used to it but the Open Office is free and there are more and more people using it now.

2) Email and Calender: Google Apps (including Gmail for organization, Google Calendar and much more)
Gmail for organization allows you to use gmail for your company’s email sending and receiving.  (i.e. you can use john@yourdomain.com on a gmail system, exactly like you are using gmail)  Google Calendar is a web-based, sharable calendar for scheduling.

3) Image Editing: GIMP
Basically a free photoshop like software. It can do what you need unless you are an advanced graphic designer.

4) Virus and Spyware Scanning and Removal: Free ESET online scanner
This is a powerful, updated, and free web-based virus and spyware scanning and removal tool.  Based on my experience, it’s much more powerful than a lot of expensive virus and spyware removal software.
