Hi!
I'm fresh off working with a Sydney based firm, helping them build custom views for their Sales team. I can get the visualforce snippet embedded onto to your Lead and Opportunities page, in under 3 hours time. I'd been working with a Salesforce ISV building apps for banking institutions. Presently I work alongside Non-Profits donning hats as a Developer, Admin and Architect.
Let me know when we can get on a call and start the customization.
Best,
Allen
