shopify store

I want to start a webpage for e-commerce store for a client with second hand clothes . I'am an online digital marketing agency and want to know offers for ongoing business.
I want he/she to be a person that is working within a timeframe and I really want to have a long term business relation .
I feel communication between us must be clear and friendly I know about costs and hours that are needed for the fulfillment and I understand that your job is very important
I live in Greece I'am a father of 3 little kids and appreciate people that are in love and passion with life .
