We need to continue working on the site on BITRIX

Good afternoon, professionals!
We are looking for a specialist in the field of BITRIX.
The previous specialist merged without explanation, although the work was paid.
The site itself has already been assembled, most of the modules have already been bought and installed - there is quite a bit left.
There is a TK with small tasks.
If we work well together, then there is another project...
Who is free? Whats the reason for what?
