You could put together a Nikon 65 spotting scope along with our 16-48x eyepiece for around $480. Thats our MSRP of course, dealer may sell for less. If you're looking for someone to inquire about it with would be P&D Enterprises out of Edmonton.
To get the 60x zoom you'd have to goto our 82 scope which would tack on about another $200
You can PM him at "P of PDent" here on the site. Hope that helps!
