Hello,
We'd love to work together on this. We are new on Freelancer.com, so let me know if we should make anything more clear. My name is Ricardo (nice to meet you) and I'm speaking on behalf of ColorElephant.
We're a digital studio based out of Portugal and we've worked on projects for clients such as BMW, L'Oreal, Microsoft or Cisco. We have an in-house team of programmers, account managers, designers and marketeers so we are able to deliver full-fledge service.
We've worked with the above mentioned companies in internal cloud-based tools as well as client-facing websites of all sizes.
Answering your questions:
1) I won't provide you with 3 suggestions, because I only think there are two which make sense: a) Shopify (you pay to use and is highly 'user-friendly') - we've done ~10 projects here. and b) Wordpress running Woocommerce which is open source and highly customisable where we have done >50 projects.
2) We know our fair share. I think on top of the store you need some content-driven part to drive visits and traffic.
We can do this and would love to. I'm happy to discuss specifics and give more details and insights. Just hit me up and we can chat or setup a call with the team. We understand this is your baby and we'd like to take good care of it.
I look forward for any feedback. Both me and my team are only an email away, and I'm open to arranging a call with the team to help set expectations.
Cheers, Ricard
