Hi Sir,
We are a team of 4 members having 4+ years of experience in magento and wordpress customization, hope we will get this job done in timely manner with 100% Quality.
We can achieve your requirement is 2 ways.
1. Using fishpig extension, so we can integrate wordpress in magento. Here you will have seperate wordpress admin to manage posts.
2. Installing blog extensions in magento to display blog posts in magento.
Though we are new to freeelance, we have enough experience in handling high level customization, since we deal with different magento requirements in our day to day activities.
Thanks,
Naren
