Re: Need some help getting into the NV world
You need to hold off on any NV gear if you budget is less than 1K IMHO there is not anything worth purchasing for that price.
The best NV scope you can get for the least amount of money is the L-3 M845 Mk$ 2.5X which would be great for hogs and/or coyotes at intermediate ranges with an IR Illuminator like the TNVC Torch Pro. This is what I would recommend for a newbie NV person interested in night hunting.

Other than that, the absolute best all around NV purchase is an ITT Pinnacle PVS-14 Night Enforcer which costs close to double what the M845 NV scope costs.
My first NV purchase that I saved up for was an ITT PVS-14 Night Enforcer, it was such a massive game changer for me I immediately started saving up for another one but they are just that damn useful and versatile. I never leave home to go night hunting without one and I have allot of NV and Thermal gear.
Clip-On NV instruments that work with day scope are expensive as are Clip-On Thermal instruments. It would be better to setup up a rifle specifically for NV use if you are on a budget, than to try to set it up for day and night use. You can use a PVS-14 as a clip-on to a scope or red dot sight, but like I said it is much more expensive than what you are considering to pay. Although anyone seriously interested in NV hunting is going to get a PVS-14....
Save up to get the M-845, is is the best introductory night vision scope you can get for the money....
