I like the 3D logos from the golf websites http://www.revolutiongolf.com and http://www.perfectconnectiongolfswing.com, nevertheless that is not a necessity.
a good idea could be the ball in yellow like the attached image one with OTI inside it
after the logo i will get a new webdesign done by 99designs as well. my new webdesign will be in an anthracite style somewhat similar to revolutiongolf.com only without a background picture
if somebody does logos and webdesign please let me know! there will also be some more graphic work to be done for the website like product logos/covers etc. in the future. please let me know if you would be available for that!
my audience is more male and probably between 30 and 55 years old on average. they live an active lifestyle
generally i want something clean and professional/serious looking...nothing too crazy with too many colors, effects etc.
it would be nice to see the logo with OTI and then the text Online Tennis Instruction next to it but also so that I can use only the OTI without the text and place the text differently in my header if i want to do that later.
the slogan for my website is "Improve Your Game" ... i am not sure if this should be placed within or right next to the logo or on the header more separate somewhat similar to how it is now at my site http://www.onlinetennisinstruction.com
as far as colors go i have no idea at this point
