Need help with Differential Equation Problems (time sensitive)

This is a time sensitive request for today 06/27/13, between 1100-1300 U.S. Pacific coast time. Please only respond if you are available during this time period. Two other projects of this nature will be available within the following weeks. I require assistance in solving approximately 5-7 differential equations. Differential equations will likely be 2nd order linear homogenous and non-homogenous. Please describe your aptitude for solving such problems in your response. Communication of problems will be handled via email attachment. Solutions should be sent back with all work explicitly detailed as each problem is solved. Thank you for reading.
