Single Parent looking for reliable help

Hello
I'm a full-time working parent looking for occasional assistance with my twin 10 year old girls. The girls attend St. Theresa's Catholic school off of Broadlands Blvd. On occasion I have a business dinner or meeting that requires me to work later than usual. On these days I need someone who can pick the girls up from school and stay home with them until I return - usually no later than 9PM. Once a year I have a work offsite meeting spanning 2-3 days where I require someone to spend the night with the girls and take them to school the following morning. I can pay and/or provide babysitting for you on weekends. Thank you
