Hi there,
Before you read the rest:
I just noticed that you've mentioned we'll have to type on the site. Do you mean we'll need to log into the server, write there, and update the changes? If yes, please count me out. Wouldn't want to waste your time with my bid. If that's not what you meant, continue reading:
I'm interested in this project. Your requirements sound fine, and I certainly know how to use articles and conjunctions - and pronouns and adjectives as well - but I have a few questions.
(1) What industry are the products in? If they're machinery parts or raw chemicals, for instance, I won't be able to write for you, since I wouldn't understand the jargon.
(2) You say you want around 6 sentences per product, for 70 products. That's fine for a general estimate, but can you provide a word count? I charge based on the number of words, and for $100 I can write maximum 6,000 words. That's 85 words per description.
(3) Is this a rush job? Descriptions are time consuming. I write approximately 1000 words per day per client, so I'd need at least 6-7 days to finish this. More if you need changes made (which will also be chargeable extra).
Thanks.
