Hello.
I can start right away.
I am an experienced web developer with more than 3 years of experience as professional software developer (mostly web developing).
I will need more details to make a time/cost estimation, and to let you know the way i am working.
Contact me for some examples of my work, if interested.
I have worked with Soundcloud before on tek-tronic.co.uk. I worked with they API, also in a different mode (I built a WP plugin where the users can add the soundcluod link and save it in the database, then display that in the site).
If you choose to work with me, i will have to know more details about what you actualy need, before i make a more ccurate bid.
Best regards, Alex.
