I am a enthusiastic digi-native with HubSpot, Hubspot's Inbound and Design (COS) certificates. I work with a number of inbound agencies with their customers' websites and inbound marketing. It means I have fixed, modified and built new pages, helped with campaigns & emails, optimized for SEO etc. so I am very familiar with the HubSpot system and the inbound methodology.
This sounds like a interesting job and I am sure that I can help you. I promise you I work hard and get things done fast, without sacrificing quality.
I would like to know a bit more about this project, e.g. is it mainly the colors you want to change or what other changes would you like? In that case, do you know what kind of changes you would like or is it up to the freelancer to come up with them?
And for the landing pages, will all/most of them use the same template or do you need multiple templates built? Once I know a bit more, by bid and estimated duration may change a bit,
Looking forward talking more about this project with you!
