Administrative assistant London

My company is a corporate health consultancy. We currently require some admin assistance over the next 2-3 weeks to prepare for and roll-out several promotional campaigns. I need assistance with collating data and creating databases.
Once the data is ready we can work together to run promotions using our campaign software. This will include creating promotional email templates and uploading databases for sending.
There is no requirement to have used campaign software before. I can assist you with training and will work with you as and when needed.
I simply need some additional resource as I don't have enough hands...!
The candidate will need to initially come to my London office but will then be able to work from home.
