Question
I know our quality of service is far superior, and I know that all the people (or at least 90% of the people) pitching lower prices than us won't be able to deliver an end product that will be of much benefit to the client (even if they do manage to fulfil the technical requirements).
We want to actually talk to buyers to figure out how and if we can actually help them, but most insist on us just sending a quote so they can screen everyone based on pricing before proceeding to discussions.
Answer
This is an old question and I hope you've pivoted since...
However, if you haven't the simple answer is to focus less on those places. You're in the low hanging fruit section of the web so you will get the low prices-- most of the time.
If you want to be paid based on your value not your time, you've gotta do what the rest of us do. :)
--Hustle to put scalable marketing systems in place.
Begin with the basic fundamentals of mapping out your ideal client, setting up an email list, and put content out there to attract them to you.
I know what it's like (as many experts here do) to get started but you'll never grow playing small.
All the Best!
