Design a 25 Years in Business Logo

My company has been in business for 25 years and I want to have a special logo design for this year.? I have never used RAC for graphic design before so I don't know how this works exactly.? I do know I want a graphic that looks nice.? "looking nice" is hard to define so you may find yourself making several logos before I am happy. My web site is [[login to view URL]][1]? I am thinking the new logo will replace the current logo.? It should incorporate the current logo and look good on the home page.? I will also use the logo in other places, including in print advertising so I will need a high res version for that.? The logo should say "Celebrating 25 Years"
