I left out two statements. Can you please consider them two?
1) As we are short of time (as the deadline is approaching), we urgently need to know if you would be interested in such a partnership.
2) If you have other proposals as to the topics to be dealt with within our research project, we are (more than??) pleased to consider them.
3) Is it a mistake to say "They have lived there since 1983 istead of they have been living there since 1983?)
