Hello
My name is Dmitriy, I'm CTO of CrowdMedia company, we love to develop complex and interesting projects. I was browsing this site for new possible projects and most of them either small or likes of "create social network site like Facebook for 100 dollars". And then I found this project. It looks interesting and it's clear that you actually thought a lot and care about your idea. I really want to see this project happen and want to help you with it, that's why I decided to post this bid.
I watched your video couple of times and read your document and I have some very important questions that may affect on time, needed to create your prototype.
First, do have a design ready? In video I can see you have neat interface, so hereafter I will assume, that you actually can provide design psds or mockups used in video, so I can create pages.
Second, whole process of purchasing credits is omitted. Do you know how clients will acquire them? As this is not mentioned nor in document or video, I assume for prototype you do not need and actual payment gateway yet.
You mention administration of artist database, there is no mention of functionality for admins to review users wishes and offers. Part about notifications need to be explained more.
I actually wanted to write some more info about how I work, tech we use and so in, but I hit character limit. Proposed Milestones are base on your pdf, just for reference, it needs to be adjusted based on information from you.
