Sounds like a magic trick (a variation of "now you see it, now you don't") except in this case the trick is not having AND having tech people, both at the same exact time according to the wording.
The problem with the wording in this ad is that both occurrences of the verb "to do" are simple present tense versions and without the use of the deictic adverb now in both clauses, it appears that these contradictory notions occur together in time.
Suggestions for improved word choice:
Now your small business doesn't have tech people, now it does. (Deictic adverb directing temporal interpretation for both clauses)
If your small business doesn't have tech people, it will now. (Present tense followed by future tense)
If your small business didn't have tech people, it does now. (Past tense followed by present tense)
