How do you handle textbroker revisions

You found my issue with many sites that only pay upfront, upfront payment alone is hardly worth it, in my eyes. However, now that you are involved, the client is the one who needs to be pleased. You seem to already be committed to the project.

On the grammar issue, Microsoft Word's grammar check system is far from fool proof. There are many grammar errors that it misses. It is also possible, your editor may not be right. Again, I would not mention that to them, they are the client. I would write the article to their specifications, make any changes they want, and be done with article sites that only offer small upfront payments.

Once on textbroker the client rejected my article saying I did not write it to his specifications. I did not revise it either since it was a long article and it was not paying much.

I personally am a member on textbroker myself. Ever since I signed up again on there and did the revision because the client wanted it and then rejected my revisions, I totally gave up on them. I suggest that you spend your time getting residual income while also getting paid for upfront such as in the case with Associted Content. I am in love with the site even though I have rejected articles where they claim I have grammar and spelling errors. I need to check up on them again.
ANyway, you should definitely check out the upfront and residual income sites. The only way to make the most money is to have your own blog where you are making money with it instead of giving full rights to the articles where you are getting paid very little for each ones. One guy I read had deleted his account at Associated Content. He was the only one who was dissatisfied. But most of us still love it.
