here they design the logo for us based on
the process starts with
1.we tell our dream to them
2.they work for us
3.finally our dream comes to live
they also provide many other services like web site design service ,brand identity design service etc...
i felt happy with their service.
Staniel made a good point about suggesting software that works with vectors. Vectors allow you to resize your logo to any size without any pixelation or loss of quality.
Adobe Creative Suite is very powerful, and for logo work, your best bet is Illustrator (vector graphics) as opposed to Photoshop (raster graphics). The real issue with this software is that there is a relatively steep learning curve, Adobe CS is software designed for design professionals ie. power users. If you hire a logo design company, don't be surprised if they are using Adobe CS themselves.
Photoshop is one of the best Logo design software. It gives the features to improve the old pictures. Photoshop has also tool to change the background. With photoshop you can also give blur effect.
There is a excellent online site called Fiverr.com that you can get almost any kind of logo, site banner, other graphics or other work done well for just $5. I have had various web banners plus ebook covers made by different people there. I also had a msword powerpoint presentation turned into an mp4 movie in two formats done. I had them done there as an inexpensive alternative to purchasing expensive software. Also I don't always have specific skills to do certain kinds of work.
I am not an affiliate there. I have just used the services. The people are great, do excellent work and are very prompt.
I hope this helps.
