Would you ref solo in summer league

[kmw]

I have been approached by a HC to ref their summer league. It would be 3 games and each game would be 20 min halves with clock stopping in second half only. I have several issues with doing it- liability being the primary issue. Would you do it?

The coach is also wanting to know what my fee would be. She just finished her first year as head coach and was a very prominent college player. I don't know if I feel comfortable enough to tell her I don't think she is going to find anyone to do it solo - but I think its the reality.
