Ongoing help with my magento website

I am looking for someone/team/business who can look after my Magento online ecommerce stores on an ongoing basis. Each job will need to be quoted for. At the moment i am looking for someone to re-design the current theme with some functionalities needing changing and adding new ones. Remote work welcome. Through PPH only. I ahve got multiple stores and this work will be on a regular basis. BUT THE QUOTES WILL HAVE TO BE COMPETITIVE.
