Sql server queries

Hello, I am looking for an experienced freelancer to help me with SQL server queries.

I will test with one query first. But would use you for others if proficient.

Example query:

Two tables joined by one column.

One of the tables contains time stamps. I want the rows split into groups whenever there is a gap of more than 5 mins between timestamps.

Eg

Timestamp

1min - grp1

1.1min grp1

2min grp1

6min - grp1

12min grp2

16min grp2

23min grp3

The groups will then have a column edited

The size of the database I need to query is medium. I would prefer someone with past experience working on similar project who understands the particulars involved in such a task. If you think you can help me out, please let me know. Thank you!
