I'm from Sydney, Australia and am currently in my last year at University of Wollongong studying graphic design. I have experience in logo design, and would be happy to share past work if you are interested in assessing the quality of my work before committing to anything.
From the look of your websites, it seems you wish to branch away from the overall name of 'Opulence Events Management' and rebrand as simply 'Opulence Management' with sub brands of Events and Weddings. If you are still happy with the design style of your previous logos, and are looking to rebrand for naming purposes, I would suggest a similar logo design with 'EVENTS' or 'WEDDINGS' below the core identity, however, if you are unhappy with the current style, I am more than happy to prototype a number of logos for you to choose from. For the sake of overall brand recognition, whichever logo you like best will provide a basis for each of the sub brands, so that your company will be easily recognisable within each section, despite differences in names.
I generally work for $30 an hour and estimate that with brand research, logo prototyping, design and up to 3 revisions, the time to complete all three logos would be close to 30 hours. I would be happy to offer a flat price for all three however at $600.
I look forward to hearing from you;
