How expensive is your product and what kind of traffic got you that 1% conversion rate?

A 1% conversion rate might be acceptable for a high ticket product (e.g. $1997), but not so much for a low ticket product (e.g. $47).

As for traffic, warm traffic (yes relationship) converts better than cold traffic (no relationship).

You should consider getting your sales copy critiqued, or even re-written. 1% generally isn't good enough to attract JV partners. Getting it up to 3-5%, and adding some stuff on the back-end, would definitely attract JVs.

As for commission rate, it depends on a number of things. Generally, 50-75% is acceptable, but again, it really depends. It's hard to say without knowing more about your product.
