The problem with those kind of websites, is that you don't know what you're getting. They allow any artist to submit designs but unfortunately some of them (not all) steal other people's designs and call it their own. This can result in lawsuits from companies that they stole the design from. I've seen this happen too many times. Why take a chance? Hire a graphic designer you trust and have them design the product for you.
That all depends. If a client does not have a colour preference and wants me to choose them, I use colours that reflect their business. For example if you offered eco friendly products, I would choose greens and blues. Also, when I present a logo to a client, I would provide several designs with different colour choices.
Your logo is your identity. You want it to reflect what you do and stand out from the rest. I good logo is simple and easy to identify with. Try to keep away from trends like web 2.0. Trends fade fast and will date your logo quickly.
A vector image is made up of paths, each with a mathematical formula (vector) that tells the path how it is shaped. An example of a vector image is an illustrator file. This file can be scaled to any size without losing clarity.
A raster image is made of up pixels therefore will lose clarity when enlarged. Raster images are best used for photos.
The resolution should be 72 dpi when sending out images through e-mail. Images with a higher resolution will increase the file size therefore taking longer to download. Since your computer monitor is only 72 dpi, the image will look the same whether it be 72 dpi or a 1000 dpi.
