Thanks for your reply Darran! Really do appreciate the advice.
What you've said is pretty much what I've been thinking, its just on the tender spread sheet that I have been sent it asks for hourly and price per job (house size) for certain jobs like needle sweeps. I've done plenty of this work to know that some houses you can go in and its a breeze and you're in and out within a couple of hours but some you're there all day finding needles everywhere and in everything. Even in the loft!
I got pretty excited I have to admit when the chance arose but since thinking about it all realistically it could go the opposite way and become a nightmare.
That's my main worry now pricing wrong, they do have a weekly retainer box in the pricing sheet which again sounds appealing but its all very vague and there's no real details on how this would all work. Thinking about leaving it at the minute to be honest, it wasn't really about the money per se it was more about the client portfolio etc
Thank you again though really helpful. If you ever need any help with anything (background in SEO and marketing) just give me a shout!
Have a good new year
