Copywriter Assistance

Copywriting assistance to produce articles (500 words) on a couple of topic areas. At the moment this is a one off job but I would like someone I can rely on in future if and when future projects come available.

Please can you quote for the following:

100 words
300 words
500 words

I will be allocating this project this evening, and as this is an urgent job I need someone that can help me out tomorrow.

Key Attributes:
SEO Knowledge
Good quality article experience
Suitable to someone starting to build a portfolio

I have stated per hour but as per context above please quote on a word basis in bid as I am likely to accept a fixed fee for producing 10-15 articles.
