SEO article writing and posting

I would invite offers for articles on the subject of our interest which is SPANISH WINE( wine, gastronomy + wine, wine growing regions of Spain etc.,) all connected to products that we sell on our store, with SEO criteria and then submitted (spinning) to multiple, specific and general sites to create quality backlinks. I would be looking for this service on a continuous basis and therefore welcome your best offers. Quality matters. Cost matters more. Cheers
