99% real followers is also a great achievement. Because most of twitter handles have 50% to 60% real followers, and you haven't mentioned your prices. How much will you charge for one tweet do you need weekly bases or per tweet bases? Giving out more information will help us to decide to buy your services.
My price depends on your offer. I give room for negotiation
I would like to receive fair payment for what I provide, to make both sides satisfied.
I also have another twitter account- with almost 6k followers but much of them are fake accounts.
(BTW. Do you know how can I check out which ones are fake and how can I get rid of them?)
