best deal for business broadband - help!

toryp63

hi - I am new to the forum and would really appreciate some advice. I am running a small business from home. We have Virgin Media but I have not been impressed with the telephone service. I want to move my office to an outbuilding at home. Currently I use my mobile for all work calls but i want to separate the work aspect from home and I want to set up broadband and phone for the business in the outbuilding. I have had a quote from BT for their business complete which is £305 plus VAT connection and installation, with a 24 month package of £55 plus VAT per month comprising 5000 mins, all local and national calls plus 0845 and 0870 calls with total broadband (not sure what that is) with an est speed of 17 mg plus £8 for the router. the monthly charge is £17 line rental 12.50 calls and 26 for the broadband. I have read the forums about BT and the complaints and I am really stuck and confused about the best way to go. I looked at BT as this is familiar and I have been disappointed with VM but I would really appreciate any advice. I need completely secure and reliable broadband as I am offering legal services so does anyone have any advice as to the best for businesses in my circumstances? many thanks in advance!
