You can check out Fiverr, I know people there will do reviews.
If this client is an established business then you want to get recent happy customers to review. That is what I do once I have the business set up in places etc. Set up an email template for them and get them to send to recent customers with some links to your preferred citation sites.
Otherwise get them to start asking new customers to review them for some ort of discount or voucher.
If they are not established then I suggest the "for hire" section on this site or the WF.
Hi,
my tool should be released in about two weeks, if you can wait about two weeks i will be selling it in the BST section according to the forum rules.
is it good to review 100 reviews using the same IP address? will it get deleted?
it is a bad idea to use the same IP, use unique IP for each review if you want them to get approved and stick.
there is a free tool at (w3).whitespark.ca/local-citation-finder/# that will allow you to find citations for keywords or a business phone number. I usually type in the phone number for the businesses that are getting front page google results for my main keywords and once the results are in I scan the list to find sites that I can get a good/google friendly citation from.
