Hello, it's Enrique, creative designer from Barcelona.
I will need the existing logo, company name, slogan if any, information about the company -activity, foundation story, actual status, businesses development expectations, competitive differentiation factors, main customers, main targets...
You will need to check the skills of the chosen designer checking his/her portfolio, references, commercial offer and previous works similar to yours at a budget you can afford.
I offer you to make a previous study before start with a brain storm. Three different proofs of logos. Amends according to your feedback. Final logo ready for web, print and multimedia. A 'Quick Start Up Guidelines' -similar to the last one I did for KitChef available on my portfolio.
Good luck with your logo design and let me know if you have any question.
Kind regards,
Enrique
