Office Interior Designer

We are looking for someone in London who can help us design the interior layout of our new office. We have a small office: 616 sq ft space, in Vauxhall, and currently have 5 staff members.

This office has not yet been refurbished from the previous occupants. There are currently partitions, but these can be removed depending on requirements and cost.

The job would be to measure the office to get an accurate layout.
Determine whether or not current partitions should remain.
Spec out furniture and help identify sources
Ideally look at things like locations of power points, internet ports, etc.

I am looking to keep a reasonable budget on this so I would like to take advantage of the myriad used office furniture sites for things like desks, pedestals and partitions.

The property managers are going to do basic refurbishment--remove screws from walls, paint and replace carpeting, so I would like to get this done sooner rather than later as changes to the partitioning might need to happen before basic refurbishment is completed.

This would be a good job for a recent design graduate looking for experience to put into a portfolio.
