Hey
I own an SEO agency and deal only with SEO and content marketing in English, Francias and Deutsche. With over 200 Audits and many other SEO practices under the belt, I can confidently say that I am up for the job.
Firstly, the budget is fair for SEO, content marketing and link building especially when I see bids that have such appalling timelines. SEO cannot be effective with such short time frames. And I suggest you take it with a pinch of salt when someone says they can do it in 30 days.
I believe the cost of this would range for a monthly maintenance between USD 2K to 6K. The number mentioned by you is like an annual retainer fee that I would gladly like to take up. However, the world is filled with conmen and I might be one. So test my services with USD 500 per month per languagefor 2 months. I will list out the things I can and cannot do during that time line. If you like what you see, lets work with a realistic pricing.
I think I can make things happen with regard to SEO. Trust me, I don't do anything else but SEO and SEO related services.
Look forward to your response.
Regards
Yogesh
