Word of advice Martin, get someone local and long standing and make sure you have contract where you have access to everything straight up all files templates and account details just in case. For ecommerce part is actually something anyone can do but how secure will it be? Most banks offering ecommerce back end software and technical support for own business customers its safest way to use banks liability not yours. Beware of freelancers your local council business link will provide you with subsidised web companies whos accredited with relavent standards and insured I had no idea about it until we got stung by cunting freelancers.
