Conducting longitudinal interaction analysis, using bootstrapping.

In relation to my dissertation, I am looking for someone with the competences to perform interaction analysis in m plus on longitudinal data, with the use of bootstrapping and checking for potential level 2 clustering effects. I would offer authorship on the article and / or payment. If someone would be interested in doing this in another statistical software, I would also be very grateful and interested.

Alternatively, if anyone have some good syntax for performing the above in m plus (I think SPSS would be a long shot for this?), it would be deeply appreciated.

Thank you in advance.
