Writing GMB description and re-writing Checkatrade page copy

I'm changing my business and I'd like my 'Business Description' for my Google My Business profile to be professionally written to a maximum of 750 characters (including spaces). In addition, I'd like the copy on my business' Checkatrade page (which I wrote) to be proofread and improved if necessary. I feel it's probably a bit wordy and any references to 'cleaning' need removing, as I now only offer a repair service. Please could you give me a quote and a rough idea on how long it'd take. Thank you.

I've attached the Checkatrade copy, but the URL to the profile is: https://www.checkatrade.com/trades/theovenrepairer
