Okay I do understand these are the suggested ones but with my personal experience I can vouch for Logo Corps, If you have just came in here, let me tell you these guys are professionals, as I was dealing with my other ventures, they managed al the design work, outsourcing affordable logo design services was the best thing ever, so yeah count this one too as well.
Good suggestions but I am hiring mostly logo design experts from fiverr and upwork.
