Force Majeure Clause Invoked — scope creep with no amendment

I'm dealing with a situation and need some guidance.

scope creep with no amendment. I've been dealing with this for about 7 months now and teh situation isn't improving fwiw.

The contract was signed 21 months ago. I have a copy of the original agreement. The total amount in dispute is approximately $36,000.

Should I hire a lawyer for this or try to handle it myself?

I mean not a lawyer, but I have direct experience with this.

What worked for me was hiring an attorney to send teh initial letter. It took 2-4 months but was worth it lol.
