Hello Cindy, thank you I will submit the update in a moment.
About the additional prize, to be fair with you actually every design I have submit it is the same - only with color variation - so basically it is one logo, but if you think you want to increase the prize it would be awesome :)
Maybe to make you more comfortable in making decision and have a more definitive answer, you could consult this matter to the site admin via contest holder section of the forum or contact them directly via contact form here
