Not too easy to answer.
For logo designs you can use any drawing program. The most simple and free one is Paint (that comes with Windows).
A google search for DRAWING SOFTWARE or LOGO SOFTWARE will find much much more. I've got no personal experience with any of them, so I can't do a recommendation.
With websites it's more difficult.
One kind is a simple static site (up to say, 20 pages) with static contents (that means, it doesn't change often and changes can be done manually). You can use software like Dreamweaver and many more. Some are more graphically oriented, others are more html-oriented.
A variant is to implement a content management system. That allows for bigger sites with a more streamlined procedure to update the contents from some kind of database that you maintain via your browser (write text, upload pictures, more or less like having a blog).
A more complex variant is a webshop where your customers can enter orders. If you've got not too much different articles a cms might suffice to contain it. If you have many different articles and many ordersit pays of to couple it to your ERP database.
So better start thinking about the kind of website you would need. Then post more details about that (and your business and your resources) in our Web Design forum. The moderator there, Sovereign, is very helpful.
Hope this helps.
I am starting my own business. I have an HP Desktop with Vista. I need to find software that will allow me to create my own logo with Vista. Just starting out I need to do everything myself.
I also know nothing about creating a website. I would appreciate any information that you can give me to get started. I do know I will need to have a website.
Thanks so much for the assistance,
