Parsing telegram channels by keywords

Good afternoon
Task: development of code for parsing telegram channels:
Get a list of feeds according to a set of keywords in your feed posts (including the part of the link separated by a period, such as "word1.word2")

Result: a working file to run in a python terminal that returns user (channel) names
Expected result of the script:
20-100 new channel titles with descriptions at daily launch.

The task assumes a complete search through the global search Telegram, through all channels and posts.

The result of a view query
"Nickname of the channel that posted the post,
Channel Description "

When I run parsing daily on the same request, I expect to receive a list of 20-100 channels.

Budget 15 thousand rubles.

In the reply, please inform us of the method and timing of the solution / similar implementations on which you had a chance to work
Thank you
