Hi there,
What a great idea of using freelancer to get feedback! Have you heard of the site usertesting.com. They allow you to pay to have people record them selves using your site and give commentary. It's similar to what you are trying to do here so you may find it useful. Anyway, we have worked with lots of websites and internal software. I'm sure we can give you some great feedback and tips (see our description below).
We're a team of 4 passionate software developers with a combined experience of over 20 years writing great software based out of Toronto, Ontario, Canada. Our team has previously worked for reputable companies such IBM, SoundCloud, and various funded Startups.
We are new to freelancing and are looking to go above and beyond our client's expectations in order to achieve 5 star reviews on our freelancer account. We purposely bid at the lowest price to make our offer more attractive to you so that we'd have an opportunity to earn a positive review from you!
Again, we really hope choose us as we're always happy to share feedback with fellow entrepreneurs, especially those launching something new! If not, we thank you for your time and wish the best with the launch of your site. Always an exciting time, good luck out there!
Regards,
The Phoenix Labs Team
