Well, I'm not gonna write you an idea for your logo, but this might be helpful. I'd recommend you to sit down and find out what you want with this logo? Is it for a business or just for own private stuff? Do a quick brainstorming and draw what ever that comes to your mind on paper. When you finally got some drawings to choose from, choose the 3-5 best of them. Now you can start making a draft of them in Illustrator or another vector program, and see which one that works best for you. It's a shortified process, but I think you got the point.
Designing ideas are perfect i think when you share it with other. when we look back on human history, one of the defining factors for our success as a species is related to our ability to work together.
The initials are probably not even the most important things of your logo. Try thinking about what you're trying to display with your logo. What feeling do you want people to have? What colors will you use? What is your website for? You should think about the message you are displaying and not just the characters.
You can scavenge around like a hobo Jew ,but if you need something professional hit me up until then good luck!
I think it's better to pay someone that knows what he's doing than try it yourself if you don't understand what a logo is about. Like I said earlier. It's not just the characters. We don't know what your message is, while that is the first thing you look at when it comes to logodesign.
I think its better for you that you can directly contact with professional logo designer consultant which guide you directly about your logo and give more better idea about it.
If you want something good, that will be the best advertisement for your site/blog/bussines you would want to pay way more than a cent. For something valuable the design is payed with 300-500$, even if you do not have that kind of a budget still you will find good designers who would help you for a lot less (ex: you had a 15$ ofer and i know people who would do it for less). Is either that or learn to use photoshop, gimp, corel, ink scape or any other image manipulation programs out there. Even if you don`t have money, you could ofer links, advertorials, a banner on your site, comments or any other service that you ofer and someone could use use it. I could make you a dozen logos with these 3 letters, but before you have a direction that you would like to use that would be a lot of time wasted from my part...
