On this snowy day I'm thinking ahead to spring, do any of you use weedman for weed/fertilizing?

I'll start by noting I know there are many people who don't agree with killing weeds and such or to have clover lawns/mixes. Totally respect your choice and opinion, but it isn't what I desire.

I have about 0.3 acre/13,000sq ft of lawn and got a quote from Weedman for $720 to do 3 weed killing application (said they would do more as needed but not sure how that works/if genuine), 3 fertilizing applications, and one surface insect control in the summer for ticks.

I normally do this myself, but it can be quite a bit of work. I've also only focused on my backyard, whereas they will do the whole lawn (front yard is dandelion city). Costing out a comparison of what it would take for me, $200 for fertilizer, $250 for weed killer, I wouldn't do the insect spray. Probably it would take me ~6 hours, so $44/hour if using the quote above.

I can afford it and have some stuff going on this year which I think it will make me go with them, even if I just try them out for the year, but I was wondering what people who have experience with them think? Are they cost effective? Do they do a good job and you've seen results? Do they increase their price quite a bit in subsequent years vs. the first year you go with them?

Thanks!
