Hi,
I have an experience for simple, clean logos as you require. Please check my profile to see some of my previous work. https://www.freelancer.com/u/alwaris?w=f
Revisions are available so you can ask me any edits or changes you need to make until the logo is confirmed by you.
Once you confirm the logo I will send high resolution vector formats and editable formats as well, vector means you can use in any dimensions without showing pixels for all digital and printing materials. Ai, eps, psd, svg, pdf, png and jpg files will be provided.
Kindly send me a message for more details, Thanks
