nuclear engineering intro/chemistry tutor wanted

Looking for a reliable and experienced tutor on nuclear engineering (intro level) or chemistry that helps me understand the said subject better, as often as possible, but no longer than 30 min each time due to other conflicting schedules, preferably at early to late night, starting immediately if possible. Located in Boston but Cambridge is a good alternate and online tutoring also works as well.

Please contact me with any information that would be helpful for me to understand the depth of your relevant knowledge and experience, along with your preferred rate. Thank you.
