Date de lancement: 02-10-2015
Date de clôture: 27-10-2015
Tout a commencé par une idée...
Un guide court et interactif les a aidés à découvrir leur style de design et a parfaitement saisi ce dont ils avaient besoin.
Brandsupply est une plateforme où des professionnels créatifs et des entreprises collaborent sur des projets et des designs uniques.
Les clients à la recherche, par exemple, d’un nouveau logo ou d’une identité visuelle décrivent leurs besoins. Ensuite, les designers peuvent participer au projet via Brandsupply en soumettant une ou plusieurs propositions. Le client choisit finalement le design qu’il préfère.
Les coûts varient selon le type de projet — à partir de 169 € pour un nom d’entreprise ou de projet, jusqu’à 539 € pour un site internet complet. Le client décide lui-même du montant qu’il souhaite investir pour l’ensemble du projet.



Here is another revision where you'll find all your answers..Like, I've customized/placed both the initial letters 'O' and 'C' inside the house as well as added 2 opposite speech bubble icons on the top of the chimney to represent the negotiation with small '$' icon placed inside of each speech bubble. hope you like it too. any suggestion?

Another revision where I've just customized both the initial letters 'O' and 'C' and placed inside just as my previous versions.

Here is the revision of my last version..I've just re-corrected/fixed my typo.

This logo featuring a nice house icon with weavy swooshes having the initial letter 'C' placed inside as hidden/negative space.
Hello Immoo,
Thank you for your participation. It's a great job .
The proposal that we find most relevant is this .
We appreciate the colors . Typography is not bad but the point of the "i" leaning .
If you want from then on he would miss the initial "O".
The buyer brokerage is present with the house but how can you bring out our negotiator side? which is also important to indicate in the logo.
Waiting for new proposals.
Cordially
Thanks for pointing out my typo..I'm sorry about that. Btw I've fixed and resubmitted the corrected version as well as some new revised versions too.

This logo featuring a circle shape splits apart into two to for both the initial letters as 'O' and 'C'..I've placed window in the middle of it to give it a real estate feel.

Here is a wordmark type of logo featuring a house icon placed inside of the initial letter "O".

Hi there CH,
Here is my first proposal in your contest..A logo featuring a customized letter "C" to form a perfect house icon with some grunge texture effects and in charcoal grey/subtle orange color scheme.
You may use this logo as a stand alone icon for your web-fevicon, mobile-app OR etc.
A unique, memorable, clean, corporate and professional logo would be good/easy for web, print and etc.
I hope you like it..Any suggestion would be welcomed.
Pls feel free to ask me anytime if you need any revision, variation OR help.
Thanks!
