I don´t know about logos for the websites, and I want to build a new one, so who can help me to have information about it?
You could spend about 50 hours of your time and about $300 to get and learn photoshop. or, you could post in the in the graphic design section and spend about $15 to have someone make a professional logo for you.
make a recognizable logo is very important, check my new logo design for my website here: http://forums.digitalpoint.com/showthread.php?t=1189178 I'm graphic designer, I can design you a professional logo for 50 $ contact me at: spidergroupchat [a] yahoo.com
Make a post here looking for a logo designer or there are many other sites that will allow you to advertise your needs for free.
You can hire someone to do a logo for you. There are a lot of professional logo designers here on DP.
I agree with letting an expert doing it for you is wiser. That's how it was for me, I got to find this site called logo corner where they designed my logo based on all my recommendations and it was great, everything I wanted. Check it out.
Is this the correct place to post this? I don't really care, but if you look under 'Services' you get a better response. Good luck!
