I currently have a VPS with servint, which has been really nice. But the only thing special I need from servint is subversion and at $50.00 per month it is not worth it.

If I can find a reseller host for around $10-$25 a month with cpanel, subversion, AND help transferring my accounts with NO downtime, I would be very happy.

I need 7-10 gigs of storage and 30-50gb of transfer

Of course the hosting company needs to be very reliable.

Did you search in the offer section? Most of the host will help you in transferring the account from the old server.

I assume you're looking for actual svn repository hosting along with the standard reseller hosting within cPanel. Unfortunately there is no automated system right now in cPanel or any add-ons to do it that I know of. I know there are add-ons in the works to do it but I doubt they'll be out any time soon.

Do you want to resell subversion accounts??

If not, then stick with a reputable reseller account for your production sites and get a separate subversion account (with enough or even unlimited projects) with a company that specialises in that field.
