You could have at least write that post without any typos/mistakes so people can take your add seriously since you said that you are "expert in English typing".
By the way, you should move this to Services section instead sharing it in Services Discussion.
I agree with you, the @OP should have improved his/her writing style before offering a service like this. I'm not in any way against the @OP, but I really think that he/she needs to improve his/her English writing skills before offering a service like this because clients often search for the services that offer high quality work , and if someone can't give quality to his/her own thread then we can expect that what level of quality they will be able provide to their clients.
I recommend you to fix the typos of your thread and also provide some free vouch copies to the reputed members of the forum who want to test such services. If you get vouches from some reputed members then you chances of getting clients will be increased.
