2.I am ready to pick up the mantle..if I find a developer, have been researching this sector for 2 months and have got a good understanding on what kind of product is required, how to launch it and carry it forward.
3.It is not a side project, this is full time, just came back form the Paris coworking europe conference and after meeting numerous space owners, software providers I feel there is huge gap in what people want and what is being provided. Secondly end users, people like you and me, are not even the focus on most of these products.
4. Someone said below the space owner can mange their marketing, space bookings etc on thier own, that is not the case, I have had completely opposite feedback.
Not sure what your objective is with the site so I have made some assumptions and here are few simple things I would do:
a)Get more info above the fold. There is so much space which can be utilised.
Ex: The left category bar can be pulled up so viewers at first glance can see the entire inventory and choose directly without having to scroll down. Give them the answer before they ask.
b)Since albums/art work are the main part of your site I would suggest getting a slider/carousel style template so you can give more info in less space. Ex: TheFilmReview.com (see how they use the slider to their advantage, not perfectly done but you get the idea).
c) Since this is a music oriented website, give it more life.
Here are a few examples how a music/band websites should look: http://www.mybandtheme.com/features/17-beautiful-layouts/
d)Single page websites, especially ones which do not have enough relevant content/information, and redirect users to other sites forcing them to purchase products are a hard sell. I would suggest once they click on one of the albums take them to a dedicated page where there is some info about the album (history/concept/production) and on that page populate your affiliate links or redirect people from there. Give users info they are seeking and that will lead to purchase.
All a quick redirect with no relevant info leads to is a high bounce rate.
