Hi there,
I just came across this post, I could do this but I would charge more than 5 an hour, but since you said you are looking for someone to work with long term, I can do this one with someone else and charge only 5 an hour, the ten hours I have estimated is negotiable.
I had look at the design you want its good, very straight forward, and having unlimited no of partitions is not a problem.
I am just looking for someone with on going projects to work with.
I am looking forward to see your reply.
Thank you,
