Promote 4 websites

We own four translation companies and we need to promote them. The overall promotion for each website must include the following: - SEO for the website - link generation - mailing campaign (here we provide the mailing lists and the email content, and you have to take care for sending them and proving to us that this was done) The SEO and link generation has to be done for all four of them as soon as possible, but the mailing should be done for one website at a time (let's say advertising one website per month) So, we will provide you our website addresses, the mailing lists and the target lists for advertising, and we need you to deal with this entire process. Please make your bid for promoting a single website, and also bid for all four websites (taking into account that the amout of work is less the 4 times if you make all of them).
