Sounds like person 1 is going to valuate and see if you want to go with them.
Person 2 is going to make a brochure including your quotes and then push you to use them as they have already done the work.

Having had an almost identical experience selling a home last year, we went with the less pushy people. We were put off buying a home through pushy people as well, as they were constantly calling with inappropriate houses for us to see (the area we said we didn't want, small gardens, no garage, overpriced...) and pushing us to see houses that were completely unsuitable when we turned up - things like being poorly extended and needed a lot of work to put right, but that wasn't reflected in the price.
