I need 10 Tech/Auto sites to submit guest post. Sites Should be DA20+

Hi,

I need 10 technology and automobile related sites in which I can submit guest post with a dofollow link back to client site.

Site Requirement:
#1 Domain Authority(DA) - 20+
#2 Site should be real
#3 No spammy sites or sites with duplicate content
#4 Sites should be recently indexed

Response with previous guest post samples will be given preference.

This can turn into a long term working relationship if everything is smooth.

Thanks,
David
