Create designs and high fidelity prototype

We are looking for an individual who can take a look at our wireframes and create a couple of new designs following our guidelines and specification . We already have some existing designs which we will provide including access to invision but if you prefer to use a different platform that's totally fine . We need the individual to take the existing designs and the new designs and create a high fidelity prototype . We will also take this prototype to the clients to get their feedback and we need that person to take the feedback and make appropriate revisions to the prototype . The first half of the project will be released when the prototype is created and the other half after we are satisfied with the revisions from customer feedback . please put read at the start of the post for us to acknowledge that you have read through the description . please include portfolio
