I am working with a freelancer in VodaBids to update my site with new logo/header, etc. I would also like to update my site so that it has a more professional look/feel. The freelancer I'm speaking with has some great ideas, but my problem is that after he edits/changes my site, I am concerned that I will no longer be able to make changes/additions using BV which is the only web development software that I know and am pretty comfortable with. This freelancer has said that I will be able to use any free html editor to change the site after it's been updated. I am very concerned that I will not know how to do this. Can I get some advise here please?
