Email marketing

I have an ecommerce store selling beachwear and resort wear. I need someone to assist with the creation of 2 weekly email/newsletters. For the right person, this would be ongoing work. Each email would need to be a different design template per week so the layout doesn't look repetitive to the recipient however they both still need to be on brand. I anticipate developing a stable of templates which could be re-used over a period of time. Copy content (provided) would be limited, there would need to be price point pull outs, calls to action throughout, different focal points on the products. Images will be provided - some are lifestyle shots on a model and others are white background shots on a ghost mannequin. Ultimately the files could be provided in jpg format. I anticipate multiple jpg's per design to allow for different design sections to link directly to the products in the website.
