New Laboratory Logo

I am looking for an experienced designer to create a new logo for my laboratory. The laboratory name is Nexlab and I am looking for a logo that utilizes cool colors (blues, greens, purples). It is important that the logo is professional and pleasing to look at. I do not have any specific elements or symbols that I would like to have included, so I am open to whatever the designer can create. Please include samples of your work when providing a quote, and provide different iterations based on feedback that I may provide. Thank you for taking the time to consider this project.

I have attached the previous logo, would like to keep the colour, but it's not a deal breaker to change.
