Description Experience Level: Intermediate General information for the website: We are a music blog submission website that rewards bloggers and labels for putting in the time to listen to thier music. Kind of development: Customization of existing website Num. of web pages/modules: 2 Description of requirements/features: I run a music blog submission website that rewards music bloggers and labels for putting in the time to listen to clients music. Here is the site: [login to view URL] (The site is NOT fully functioning as yet as there was an issue with the original designer of the website. I am not seeking someone to carry on from where he left it). 1. Premium credit system: (How it works) This is for clients who wish to submit there music to music blogs via submittoblog.com. Bloggers get rewarded for reviewing submissions. Music Bloggers receive 40p for every submission they review and leave feedback for. When a customer buys premium credits, their submission filters to the top of that blogs dashboard. The blog you send to has to then: 1. Respond within 48 hours 2. Listen to at least 20 seconds 3. Approve the song or provide a minimum of 10 words explaining why it wasn’t a good fit. If they don’t satisfy these requirements, the customer can get their credit back into their account to use again. STANDARD CREDITS: (FREE) With standard credits there are no such functions. A blog can choose to provide feedback if they wish, but may instead make a quick decision and move to next song PREMIUM CREDITS: (COST) Premium credits start at £1 and get cheaper as you buy more in bulk. Each credit will allow you to send a song to one blog. With ten credits, for example, you can send your song to 10 blogs in one easy submission. Right now the tiers include: £40 for 50 credits £25 for 30 credits £9 for 10 £5 for 5 Also.. I need this doing: 2. APPLY TO JOIN [login to view URL] Once they complete the application form to apply to be listed as a blog via submittoblog, the website to notify by email automatically if they are successfully approved by admin. The admin panel should show all applications where admin can 'approve' or 'disapprove' applications. [login to view URL] Similar urls: [login to view URL] Extra notes:
