Companies that create private porn movies with porn stars

[tftsc]

I am looking for companies with a website that offer the production of private porn movies with a pornstar.

So far I have found:
Premium Link Upgrade
a site that offers adult movies with various uk porn stars

Premium Link Upgrade
a Japanese site where I can't navigate nor find the girls they work with.

Does anyone have more links of companies like these so I can make up my mind on which one to go for?
Thanks in advance.
