Hey there!

I also am rebuilding my profile as I took on too many projects last holiday season and was too overwhelmed to even email them that I couldn't do it. In efforts to rebuild my score (which was very good at one point). What I have done is request a shop and right away I send an email to the scheduler explaining that I know my profile shows a lower score right now. I concisely and professionally explain why my score is low and then I assure them that I am committed to the shop I'm requesting. Bonus points if you can speak on your experiences or steps that you will take to ensure you'll do it well.

From there I would commit to doing the shop both on time and well.
