Based on my sketch/wireframe prepared for a UI designer (links below):
1) Would I be able to approach a UI designer with the wireframe/sketch above?
2) What are the concerns that I should have between wireframe -> UI design -> front-end development?
You can certainly approach a UI designer with what you have.
The concerns I’d have is that UI design, Wireframing, Prototyping, Interaction Design, Content writing, Development, etc all influence each other.
In other words, it’s very difficult to do any one of those tasks in isolation of another.
Wireframes can’t fully predict all user flows. They can’t stipulate all the interaction design. Sometimes the UI design leads to a solution that would change the wireframes, etc.
So, as long as you are OK with keeping the documents ‘loose’ I think you’ll be fine.
