Upsell Paid Subsciption when User registers to the forum

[coolMax]

Hi,

Is there some sort of mod that I can implement into my forum where when visitors register to the site on the register page itself there are options for the visitor to upgrade to one of the paid subscriptions (silver, gold, platinum)?

If they do decide to upgrade, it would take them through the whole payment process via PayPal.

I couldn't find anything out there like this. If there is please direct me to it, or if not, I'd be willing to pay to get this customized on my site.

Thanks.
