Greetings!
Thanks for inviting me to this job! I would love to be able to help out with the photography, though my only concerns are when and how long.
I am booked this weekend and the next weekend, but will be available after that weekend. Basically, any day after June 1st. If your birthday party has happened by then, I'll be unable to come, unfortunately, but wish you a happy birthday!
Feel free to contact me for any questions or concerns,
~Jess
