I am looking for a part time virtual assistant to assist with a range of tasks varying from approx. 5-20 hours per week, depending on capabilities.

The business retails DSLR film making equipment on our website www.fastforwardtime.co.uk as well as ebay and amazon. Some knowledge of DSLR film making (or at least a willingness to learn) would be highly advantageous.

The VA will need to be confident to carry out the following tasks:
1) Responding to emails/ eBay messages, using a standard q&a template for many of the questions.
2) Making a few calls to chase suppliers etc.
3) Creating purchase orders (using a template)
4) Managing our twitter page, responding to and interacting with customers.
5) Browsing industry related blogs, adding links to our website along with some relevant information/comments.
6) Manipulate exel spreadsheets, adding information etc.
7) Modifying & repricing ebay /amazon listings.

Ideally (but not essentially) the VA will be also able to:

8) Carry out web design tweaks (we use and opencart based website)
9) Write articles on dslr film making for our blog
10) Answer more technical questions relating to dslr film making.
11) Negotiate with suppliers on skype.
12) Get more involved with SEO and link building.
13) Write product description listings.
14) Write email newsletters.
15) Photograph products
Please respond to this job by stating which tasks you feel you will be capable of, and any relevant experience you have had.
This job request is for 2 hours of work. If this goes well, I will open more jobs on people per hour on a weekly or monthly basis for longer periods of time, eg for 5 or 20 hours of work.

Thanks for your interest in the job.
