Dear sir
Good day
I have 12 Year experience in Information Technology, Internet marketing and SEO.
By just adding SEO, to your website, it will not make much improvement.
I will create a Android Web view app, with progression dialogue functionality for you.
App name need not to be same as website, you can keep your product or service name.(Alternate way to attract traffic)
And I will create a Facebook page with button, when someone click on the button, it will take them to your website. (Alternatively you can run the same page as paid campaign when ever you need)
Also I will create a Google search console account and add SEO keywords, to your website for appear in 1st page of Google search engine in few days, comparing your compititer keywords will be created.
Finally your company and Website will be advertised in few Classified according to your preferred audiance location.
1. Android app
2. Facebook page
3. Google search console, SEO keywords
4. Classifieds advertisement
Altogether 150€
Now the choice and decision is yours
Thankyou
