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 and we've also helped people wanting to start their business by bringing their ideas to reality. Working with us you get assigned an Account Manager which will oversee the whole process and help you along.
We have done similar projects (for ourselves - as we run our own SaaS software -and clients) and happy to help here. For the tool, clearly UnBounce would be a suggestion. Let me know if you'd like and we can chat further on this.
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,
Ricardo
