Can you solicit services from me?

Can you solicit services from me?

For example, if I want to do SEO for a Japanese website, it is time-consuming to make inquiries one by one to see if it is possible to handle the job.

So, is it possible for me to publicly announce that I would like to do something like this done and recruit?
If possible, where can it be done from?

I am using a translation site, so there may be some strange words.
