I will help you improve the UX of your website/application by doing the following:
1) Evaluate your design according to a set of heuristics
2) Prepare a report and suggest improvements on your design.

Things I will need from you:
1) A brief discussion about your users, business, and goals (over skype of chat whichever you prefer).
2) Link to your website/app which you want to be evaluated.

You will get a report from me after I am done with the evaluation containing:
1) usability problems in your interface
2) their severity level (this helps you determine which ones you need to prioritize)
3) and design suggestions.
