Small changes to existing logo

Hello, we are looking for help to make small updates to an existing logo design to give it a refreshed look. The current logo uses the business name in the form of a panel sign, it is quite simple. We already know the adjustments we would like to make and are looking to test some options in terms of size and colour, so the potential revisions will be limited. The selected designer will be provided with high resolution files of the current logo to work from and asked to provide 3 final versions in different colours in high and low resolution, and in different formats for print and online. Important to have a good eye for details. Compensation will be commensurate with experience and quality of submissions and on a per hour basis (estimated around 2-3 hours). Many thanks in advance for your kind offers.
